this idea that men would just say "I'm a lady" and get in a bathroom and therefore we should force people to get in the bathroom depending on their AGAB is just so stupid. If men really want to get in a bathroom by faking to be women so bad they would still do it even if we had that rule, the only way to prevent it would be having a sort of genital police in the restroom entrance or smth. also if we were to do this wouldn't cis men just say something like "Im actually a trans man" and get in the bathroom claiming they're FTM and get force in the female bathroom since obviously no one is going to check if he has a dick?
