From that right wing publication The New Yorker :
But there is also a growing sense that some females will not feel safe sharing bathrooms, shower rooms, or locker rooms with males. And if a female student claimed that a bathroom or locker room that her school had her share with male students caused her to feel sexually vulnerable and created a hostile environment, the complaint would be difficult to dismiss, particularly since the federal government has interpreted Title IX broadly and said that schools must try to prevent a hostile environment.
No shit, Sherlock.
