Never thought of that, actually...

Idk. . .

Great question, idk

Well, considering JKR, maybe there are none in Hogwarts (maybe even in the Wizarding World)

^^True. She’ll probably say ‘MaGiC dOeSn’T pIcK pEoPlE lIkE tHaT—’

I am guessing that Rowling would have never considered that. They would probably have to stay in the dorms that match up with the genders on their birth certificates or something :(

^exactly what I had in mind. It would apply for the people who aren't either male or female as knowing J.K. she probably never considered what would happen in that case

That's actually really sad
