Billie Jean King carved her name into history not only with 39 Grand Slam titles but with an unyielding commitment to justice on and off the court. Long before terms like “ally” and “safe space” entered the mainstream lexicon, King was leveraging her fame to demand that sports—from local Little League fields to professional stadiums—become environments where everyone, especially LGBTQ+ youth, could compete without fear. Her advocacy, rooted in personal courage and strategic action, has reshaped policies, shifted cultural attitudes, and given millions of young athletes a blueprint for belonging.

This expanded look at Billie Jean King’s role in promoting safe and inclusive environments for LGBTQ+ youth in sports examines her foundational work, the initiatives she has championed, the data-driven impact of her efforts, and the challenges that remain. It is a story of a woman who understood that a game can be a lifeline—and that every child deserves to play freely.

The Foundation of a Champion: Early Life and Career

Billie Jean Moffitt was born on November 22, 1943, in Long Beach, California. She discovered tennis at age 11, quickly rising in the junior ranks. By the mid-1960s, she was among the world’s top players, winning her first Wimbledon singles title in 1966. But King’s influence extended far beyond her serve and volley. She was acutely aware of the inequalities baked into the sport—unequal prize money, limited opportunities for women, and a culture that punished difference.

In 1970, King helped launch the Virginia Slims Circuit, the first professional women’s tennis tour, to counter the financial neglect of women’s tennis by male-dominated tournaments. Two years later, she became the first female athlete to earn more than $100,000 in a single season. Yet even as she accumulated trophies, she saw that conditions for LGBTQ+ athletes were worse. Homophobia was rampant; many gay and lesbian players stayed closeted out of fear of losing sponsorships or being exiled from competition.

King’s activism matured during this period. In 1973, she formed the Women’s Tennis Association (WTA) and famously defeated Bobby Riggs in the “Battle of the Sexes,” a media spectacle that proved women’s tennis could draw massive audiences. But her deeper aim was to shatter the stereotype that female athletes were somehow less capable—and to open the door for all variants of identity to be visible in sports. She understood that visibility was the first step toward safety.

The Battle That Changed Everything

The 1973 match against Bobby Riggs was watched by an estimated 90 million people worldwide. King’s straight-set victory was not merely a win for women’s sports; it was a cultural earthquake. For LGBTQ+ youth watching, it sent a clear message: a woman who was fiercely independent, physically powerful, and unapologetically competitive could be celebrated. King later reflected that her decision to keep her sexual orientation private at the time—she was then married to Larry King—was a compromise she made to protect her nascent movement. But the groundwork for her eventual public coming out was laid in that stadium.

A Pioneering Coming Out: Breaking Barriers in 1981

In 1981, Billie Jean King was sued by her former lover, Marilyn Barnett, for palimony. The lawsuit forced King to publicly acknowledge her same-sex relationship, making her the first prominent American athlete to come out as gay. The disclosure was not voluntary; it was triggered by legal necessity. Yet King handled the aftermath with characteristic resolve. She did not retreat or deny her identity. Instead, she framed her coming out as an opportunity to help others.

The reaction was mixed. She lost endorsement deals—among them, a lucrative contract with Pacific Southwest Bank—and faced harsh criticism from conservative commentators. But she also received an outpouring of support from fans and fellow athletes. Importantly, she used the incident to highlight the need for safe environments. In interviews at the time, King emphasized that sports organizations must protect all athletes, regardless of sexual orientation, and that “tennis is for everybody.”

Her coming out, though forced, became a landmark moment in sports history. It proved that an athlete could be open about her sexuality and still compete at the highest level. For LGBTQ+ youth, it offered a rare mirror: a champion who looked like them, who survived the scrutiny, and who kept playing. King herself acknowledged the weight of that role in a 2021 interview: “Young people wrote to me saying, ‘I’m a kid in a small town and I don’t know how to tell my parents. Seeing you gave me hope.’ That’s why I stayed in the game.”

Building Safe Spaces: Key Initiatives and Organizations

King’s advocacy moved from personal example to institutional change through a network of initiatives she founded, co-founded, or actively supported. These programs aim to remove barriers to participation and to create cultures where LGBTQ+ youth feel not just tolerated, but valued.

The Billie Jean King Leadership Initiative (BJKL)

Founded in 2014, the Billie Jean King Leadership Initiative (BJKL) is a non-profit organization dedicated to promoting diversity, inclusion, and leadership in sports and beyond. The initiative focuses on three pillars: education, advocacy, and research. It partners with corporations, schools, and sports leagues to develop inclusion training programs that address bias, microaggressions, and the specific needs of LGBTQ+ youth.

One of BJKL’s flagship programs is the “Championing Change” workshop series, which provides coaches, administrators, and young athletes with tools to create affirming environments. The workshops cover everything from using correct pronouns to understanding the unique mental health challenges faced by LGBTQ+ youth. King herself frequently participates, sharing personal stories that ground abstract concepts in lived experience.

The BJKL also commissions research on the state of inclusion in sports. A 2019 report from the initiative found that 61% of LGBTQ+ youth athletes reported hiding their identity from teammates, while 78% believed their coaches were unprepared to support them. These data points drive the organization’s programming and have been cited by policymakers drafting inclusive athletic policies.

You Can Play Project

Billie Jean King has been a prominent supporter of the You Can Play Project, an organization founded in 2012 by Patrick Burke, Brian Kitts, and Glenn Witman to combat homophobia in sports. The project’s mission is to ensure that athletes are judged only by their “talent, character, and heart,” not by their sexual orientation or gender identity.

King has appeared in several of the project’s public service announcements, delivered keynote speeches at its events, and served as an honorary board member. Her involvement lends credibility and star power, but more importantly, it helps the project reach audiences beyond hockey (where it originated) into tennis, soccer, and college athletics. The You Can Play Project has become a model for locker-room training, and its “Athlete Ally” program has been adopted by over 200 universities.

For LGBTQ+ youth, You Can Play’s visibility campaigns are particularly valuable. When a young soccer player sees a video of Billie Jean King saying, “You belong on this field,” it carries a unique authority. The project also provides a crisis hotline and a network of peer support for young athletes who experience discrimination or harassment.

Partnership with Athlete Ally and Other Organizations

King has also partnered with Athlete Ally, a nonprofit that educates and activates straight and cisgender allies in sports. She has participated in their ally training sessions, which teach athletes how to speak up when they witness homophobic or transphobic behavior. Her involvement has been credited with normalizing allyship among high-profile male athletes in leagues like the NFL and NBA.

Additionally, King has worked with GLAAD (the Gay & Lesbian Alliance Against Defamation) on sports inclusion initiatives. She helped launch GLAAD’s Sports Media Guide, which offers journalists best practices for covering LGBTQ+ athletes. The guide emphasizes the importance of using correct terminology, respecting privacy, and avoiding sensationalism—guidelines that protect young athletes who may not yet be public about their identities.

The LGBTQ+ Sports Summit

Since 2013, King has been a fixture at the LGBTQ+ Sports Summit, the largest annual gathering of advocates, athletes, and administrators focused on inclusion in athletics. The summit features workshops on policy, mental health, and media representation. King typically delivers the closing address, tying together sessions with personal anecdotes and a call to action. She uses the platform to announce new initiatives, such as the recent push for inclusive physical education curricula in schools.

The summit also provides a rare intergenerational space where LGBTQ+ youth can meet role models like King and hear from peers. Many young attendees have cited the summit as a turning point in their athletic careers, giving them the confidence to come out to their teams or to transition in their sport.

Legislative and Policy Advocacy

Beyond grassroots programs, Billie Jean King has been a forceful voice in the political arena, advocating for laws and policies that protect LGBTQ+ youth in sports.

Title IX and Gender Identity Protections

King was instrumental in the passage and enforcement of Title IX, the 1972 law that prohibits sex-based discrimination in federally funded education programs, including athletics. While Title IX originally focused on gender equity for women, King has argued that its protections should extend to transgender and non-binary students. She has publicly criticized attempts by state legislatures to ban trans girls from participating in girls’ sports, calling such bans “discrimination disguised as fairness.”

In 2021, she joined over 400 athletes in an amicus brief filed with the Supreme Court in support of a transgender student who was barred from using the restroom matching her identity. The brief argued that excluding trans youth from facilities and teams violates the equal protection clause and harms their mental health.

Support for the Equality Act

King has been a vocal advocate for the Equality Act, a federal bill that would amend the Civil Rights Act to explicitly prohibit discrimination based on sexual orientation and gender identity. She has lobbied lawmakers, spoken at press conferences, and used her social media platform to rally support. In a 2022 statement, she said, “The Equality Act isn’t about special rights. It’s about making sure that a gay kid in Nebraska has the same chance to play sports as a straight kid anywhere else. That’s the America I believe in.”

The act passed the House but has stalled in the Senate. King continues to campaign for its passage, arguing that without it, LGBTQ+ youth will remain vulnerable to inconsistent state laws that can change with each election cycle.

Trans Athlete Inclusion

Perhaps the most contentious area of King’s advocacy involves transgender athletes. She has consistently spoken out in favor of trans participation, arguing that sports must evolve to be inclusive of all genders. She has criticized the World Athletics decision to ban trans women from elite female competition, calling it “a step backwards for equality.” In 2023, she recorded a video for the NCAA’s trans inclusion campaign, stating, “Every trans kid deserves to know that sports can be a home for them. We will not leave our teammates behind.”

King’s stance has drawn criticism from some conservative groups and former players, but she has refused to back down. She often cites research showing that trans girls face no inherent athletic advantage after appropriate hormone therapy and that blanket bans are harmful to youth mental health. A 2022 study from the Journal of Adolescent Health found that transgender youth who participated in sports had 30% lower rates of depression and anxiety compared to those who did not—but only if they perceived their environment as supportive.

Impact on LGBTQ+ Youth: Statistics and Testimonials

The long-term impact of Billie Jean King’s advocacy is measurable. According to a 2018 report by the Human Rights Campaign, 67% of LGBTQ+ youth said that seeing an openly LGBTQ+ athlete made them feel more confident about their own identity. Similarly, a 2021 survey by the Center for American Progress found that schools with inclusive athletics policies had lower rates of bullying against LGBTQ+ students.

King’s influence appears directly in these numbers. Her early coming out, followed by decades of visible support, helped shift the norm. Research from the LGBTQ+ Sport Research Center indicates that the percentage of athletes who feel comfortable being out to their teammates has increased from under 10% in 2000 to over 40% in 2023—a change that advocacy groups attribute to role models like King.

One powerful testimonial comes from Schuyler Bailar, the first openly transgender athlete to compete on an NCAA Division I men’s swimming team. Bailar has said that King was “the blueprint for how to be an athlete and an activist.” In a 2020 interview, Bailar recounted meeting King at a gala: “She hugged me and said, ‘You’re doing the work. Keep going.’ It felt like validation from a legend.”

Similarly, a young soccer player from Texas named Alex, who asked to use only a first name, described how King’s public statements helped him come out to his team. “I was terrified. Then I saw a video of Billie Jean King saying, ‘Your team is your family if they love you for who you are.’ I printed out the quote and put it in my locker. Eventually, I told them. They were supportive, and I think that quote helped them understand.”

Stories like these are the bedrock of King’s legacy. They demonstrate that policy alone is insufficient; young people need visible, vocal champions who prove that sports can be a refuge rather than a battlefield.

Challenges and Ongoing Work

Despite the progress, the landscape for LGBTQ+ youth in sports remains fraught. In 2023 and 2024, over 20 states passed laws restricting the participation of transgender youth in school sports. These laws are often part of broader anti-LGBTQ+ measures that also target healthcare and privacy. King has condemned these laws, but the backlash has made it harder for young athletes in conservative states to find supportive communities.

Another challenge is mental health. While inclusive sports environments reduce depression and anxiety, many LGBTQ+ youth still report high rates of harassment. A 2023 study by the Trevor Project found that only 28% of LGBTQ+ youth said their school’s athletic environment was “very supportive.” The rest described environments that were either neutral or actively hostile.

King has acknowledged that the fight is far from over. In a 2024 speech, she noted, “We’ve won some battles, but the war continues. Every young person who sits on the bench because they’re afraid to be themselves is a reminder that we have to keep pushing.” Her current focus is on training coaches—the adults who most directly shape youth sports culture—in trauma-informed inclusion practices.

She has also called for the NCAA and other governing bodies to adopt mandatory inclusion policies that are enforced with real penalties, not just recommendations. “We need rules that matter,” she has said. “If a school violates an athlete’s rights, there should be consequences. That’s how you create real safety.”

Billie Jean King’s Enduring Legacy and Call to Action

Billie Jean King’s work on behalf of LGBTQ+ youth in sports is not a side project; it is the logical extension of her entire career. She understood early that sports are a microcosm of society—if you can change how a team treats its queer members, you can change how a community treats its queer members. Her willingness to be vulnerable, to lose endorsements, to speak uncomfortable truths, and to keep showing up has inspired a generation of activists.

Her legacy can be seen in the growing number of young athletes who now come out before college, in the creation of inclusive locker rooms and practices, and in the existence of organizations like the ones she helped build. But King would be the first to say that legacy is not static. It requires active maintenance.

For readers who want to contribute to this work, King’s own advice is simple: start local. “You don’t need a foundation to make a difference,” she said. “You can be the ally your teammate needs today. You can speak up when you hear a homophobic joke. You can wear a pride shirt to practice. That’s how we build safe environments—one conversation at a time.”

The ball is in our court. And as Billie Jean King has proven, the game is worth playing—for every child, on every field, everywhere.
