A dozen U.S. colleges and universities, including five Ivy League schools, have all-gender restrooms and locker rooms, the New York Post reported.

The Post cited a report from Critical Race Training in Education, a conservative advocacy group affiliated with Legal Insurrection.

"Our research continues to reveal the depravity and institutional capture of higher education," CriticalRace.org managing editor Kemberlee Kaye told the Post.

"These are no longer places where ideas are debated, where intellectual furtherance exists, instead, they're dangerous and hostile to the point that women are not guaranteed single sex safe spaces to shower or use the facilities," Kaye added.

The schools cited are Brown, Columbia, Cornell, Dartmouth, the University of Pennsylvania, University of California, Santa Barbara, Cal State Polytechnic Humboldt, Carnegie Mellon, Florida State, Stanford, Stony Brook, and Villanova.

Some of the schools have more than 50 all-gender restrooms or changing rooms that are open to all users, including transgender and nonbinary people.

"No woman should be forced to change in front of a man — this is not and should not be controversial," Kaye said.

William Jacobson, the founder of Legal Insurrection and a professor at Cornell Law School, one of the 12 schools named, warned the schools could face complaints and a loss of federal funding.

"No decision has been made but certainly we are investigating potential Title IX violations," Jacobson told the Post.

"This raises significant Title IX issues and possible violations, particularly in light of the recent Supreme Court interpretation of Title IX regarding boys in girls' sports. 'Gender identity' does not override female rights as a matter of federal law," he added.

"Female spaces are being invaded in the cause of gender identity," Jacobson said.
