This is a kind of inverse P.C. which is why it goes nowhere.
In practice, if impostors who do it well visit the rooms for what they masquerade as, few complain. It’s happened for decades. But the question arises about how to police this? Are birth certificates needed to go in the loo? Do I have to show my thang as a passport? What we are lacking now is respect, which the impostors of old still had. This sounds like a disorderly-conduct issue. Don’t get up like a squishysexual freak and then showily go to a public loo.
The problem today is a man for instance can identify as female on any given day WITHOUT dressing like one to use the ladies room.
I know we all have visions of ugly cross-dressers or Ruepaul types but that is simply not the case all the time.
This insanity also carries over to schools.
