Cis people and idiotic bathroom takes

Some guy I know was telling me all about how bathrooms should be based of genitals and nothing else. Going on about how he'd beat the shit out of any "man" (referring to trans women) he saw "follow a woman into the bathroom." He dragged this up out of nowhere.

First off, nobody wants to see a passing trans man in the woman's room.

Second, do cis people think women's bathrooms are maximum security prisons? Do they not realise that a man could just walk in there without transitioning to female?

Sorry to beat this topic further into the ground. I'm just once again amazed by the lack of critical thinking skills of people on the far right.
