evidence: In 2019, the University of Pennsylvania's swim team informed its female athletes that Lia Thomas, a man formerly known as William Thomas, would be competing alongside them. But the consequences of the university's decision wouldn't be limited to unfair competition. Although Thomas' teammates were told he would use separate locker-room facilities, he was instead allowed to use the same locker-room as the rest of the team, subjecting the all-female group to changing clothes in front of a man. This incident, and the University of Pennsylvania's intense crackdown on dissent, sparked many of its athletes to come forward and advocate for the future of women's sports.
