I don't believe that in most jurisdictions there were laws about who used which restroom. Indecent exposure and lewd and lascivious conduct was, and still is, illegal.
Yes, it is. So why do men suddenly think they can enter the ladies restrooms and locker rooms? Because they have been been told that they legally can do it. It's removed a barrier and created direct access to a boundary condition. Disturbed men are acting on it.
Question - if a transgender man is using a women's locker room and exposes his penis to a young girl, he's committed a pretty serious sex offense hasn't he? Basically he is no different than the flasher in a trenchcoat.
I would not be surprised if most of these recent ones which were not obviously perverts, were probably conservatives making a political statement. This too will pass.
You think someone deliberately took actions to get themselves registered as a sex offender for the purpose of pointing out that it was possible? Do you realize how laughable that sounds? Go back and re-read it with a neutral mind and try to fight off your embarrassment at what you wrote.
No, it isn't going to pass, it is going to get worse. Here's another one that I missed, it just showed up in the "past 24 hours" search. Man filming a 10 year old girl.

I believe I also missed one about a man assaulting a 8 year old girl in a Chicago ladies bathroom in a Jason's Deli. Again, the barriers to him being in the bathroom were broken down and that put him and his victim alone in the bathroom.
Do you know where I haven't seen one of these stories? In North Carolina.
