My thoughts is that it’s a simple situation really. If they’re harassing or assaulting people, the women will call the cops or something, simple situation and get the guy arrested. If he’s not doing anything, it’s nothing harmful. Apparently that’s not a solid enough answer. What should I have said?
Irrelevant but: I, um, did this once. We were at a fancy art gallery. I somehow followed what I thought was a mixed group into what I thought was a general bathroom. I remember thinking “what a novel concept to mixed bathrooms this is!”
It was only afterwards that I realised that, no, this was not a mixed bathroom. No one said anything, but I cringe at myself and at how uncomfortable I must have made people feel.
