the idea that restrooms, locker rooms, etc need to be single-sex spaces in order for women to be safe is patriarchy's way of signalling to men & boys that society doesn't expect them to behave themselves around women. it is directly antifeminist. it would be antifeminist even if trans people did not exist. a feminist society would demand that women should be safe in all spaces even when there are men there.
i think its so funny that alumni from schools like harvard and columbia that were there during the protests in the 60s-80s are expressing support for students currently protesting against the genocide in palestine, and random zionists that were NOT at these protests in the 60s-80s have the never ending audacity to tell these alumni "well thats different, what you protested was good and what they're protesting is bad." as if protesters against the vietnam war and apartheid south africa were not also demonized, arrested, brutalized, and even killed for their activism. history only remembers them fondly after the damage has already been done.
