First, it's NC, not SC, thank you.
Heard an explanation of the Fed's position this morning. They say Gender Identity is the same as race, under the Civil Rights Act of 1964. If a man who "identifies as a woman" wants to use the women's locker room or bathroom, you must let him. By extension, if the same man wants to live in the girl's dorm at college, you must let him. Play on the girl's team, join a sorority, use the girl's dressing room, and on and on. No discrimination or exclusion because of gender identity.
And if any state doesn't comply, they can lose any/all federal funding for any/all programs.
