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?
This is not even a good question to argue with, if anyone in the restroom is being a creep it's not ok and that's that.
