You are completely misrepresenting what these legal protections allow and don't allow. Regardless of the law it has always been and will continue to be illegal to enter a bathroom with the intent to harm others. Can you cite some instances of transgender people harming anyone in a public facility? As long as where inventing fanciful scenarios how about this one, in NC under HB2 a man would no longer even need to pretend to be a trans woman to enter the ladies room. He only needs to claim to be a trans man who transitioned from female to male and then he can enter with a full beard and his regular clothes, no dress needed.
