This is for anyone to answer, but if you do, please stick to my question and don't get into politics, religion, haters, bigots, backlash, etc. concerning "bathroom bills".
The setup: a state passes a law requiring people to use restrooms consistent with their birth sex.
Question: is it really enforceable? How?And who does the enforcing?
Have you heard or read (in the law or media) about the enforcement mechanism?
