Eh. Am I the only one who thinks that trans or not, gendered washrooms are pointless? In my new school building, there's one two-stall washroom for students, unisex. And it's the first time I've ever used toilets that were almost always in an acceptable state of cleanliness. I love it, save for the lack of space and single sink right next to the opaque, dangerous door.
Guys have just learned to do like at home and pee like human beings (=inside, not on, the toilet) out of respect for the women. And guys who need to poop or sit to pee are probably grateful too.
