Christian colleges are some weird things, I don't know anything about them. Like the idea of a male-only dorm is pretty foreign to me, being used to dorms in which men and women can live in and use the same bathrooms.
Anyways it's a bit of tricky issue. Like one part of me says that they should let him live in the male dorms, that their suggestion that he live in his own room or off-campus is effectively them quarantining him. It's also a safety risk, I think, because isolating him like that is not something that's going to go down lightly. Schools need to prioritize the well-being of their students so if they can argue that living in a male dorm would put him or others at risk, then it becomes a bit more complicated, especially considering that they're a private college.
All in all, I don't know man.
