Friends,

Men and women are physically different. That reality is grounded in biology, reflected in science, and made unmistakably clear in athletics. Women’s sports were created to ensure fair competition and equal opportunity for female athletes—not as an abstract concept, but as a practical necessity. We all knew this a few years ago.

Today, that fairness is under serious threat. When male athletes are allowed to compete in women’s sports, women lose championships, records, podium finishes, scholarships, and opportunities they can never get back. The false claim that men can change their sex carries real and lasting consequences, and those consequences are being borne by women and girls.

That’s why Mississippi and other states have passed laws protecting women’s sports by making participation contingent on sex. These laws reflect basic biological reality and preserve the very foundation on which women’s athletics were built. Now, those protections are before the U.S. Supreme Court.

This week, the Court heard arguments in cases from West Virginia and Idaho, two other states that have chosen to protect women. After more than three hours of oral arguments, several justices appeared skeptical of claims that laws keeping men out of women’s sports violate the Equal Protection Clause or Title IX.

I love the common sense comments from our Supreme Court justices. 

Justice Samuel Alito pressed attorneys challenging the laws on a fundamental question: what does “sex” mean? When they couldn’t answer it he asked, how can courts possibly determine whether discrimination exists? Chief Justice John Roberts echoed that concern, emphasizing that Title IX’s prohibition on sex-based discrimination must have a concrete meaning.

Justice Brett Kavanaugh highlighted another reality often ignored in this debate: sports are a zero-sum game. Even a single male athlete competing in women’s sports can dramatically alter outcomes, displacing female athletes who have trained for years. He also noted that states are actively debating this issue, with more than half choosing to protect women’s sports through law.

These arguments underscore what female athletes have been saying all along: fairness matters, biology matters, and equal opportunity cannot exist without clear boundaries.

The stakes go beyond trophies and titles. These cases could shape how states protect women’s privacy and safety in locker rooms, bathrooms, and other sensitive spaces. They will determine whether women’s sports remain places where female athletes can compete on a level playing field.

Outside the Court, I was proud to be one of the many Americans who showed just how much this issue matters. Women (and men) traveled from across the country to stand up for the obvious principle that women’s sports should remain for women.

The Supreme Court now has an opportunity to affirm biological reality, protect equal opportunity, and preserve fairness for current and future generations of female athletes. This moment will define the future of women’s sports nationwide. And it’s one worth paying close attention to. And it’s one we have to get right!
