But there is a solution. Penn’s female swimmers could boycott all future competitions that include Thomas and refuse to compete for a school that will not guarantee them the standard of fairness that is their right.

Of course, this would require courage — and lots of it. The school could retaliate and revoke athletic scholarships, and individual swimmers might lose opportunities to swim professionally if they don’t compete. There would also be immense backlash from the Left, which seeks to punish anyone who challenges transgender orthodoxy.

But what’s the alternative? Not one girl on that team will win a race as long as Thomas is competing against them, which means they are already losing athletic and professional opportunities. And if women don’t begin to stand up to this radicalism now, while it’s still in its infancy, women’s sports as we know them will be gone for good. There will be a Thomas on every single high school and college and professional female sports team in the country — and think of how many girls will have lost athletic opportunities as a result.
