What would you do if you saw a man follow your daughter into the bathroom?

Does anyone else see the absurdity of all of this? So NC passes an unenforceable law. Unenforceable? Think about it. People only are permitted to use a public restroom based on the gender specified on their birth certificate. Yes, that law. How would you enforce it? A person who appears to be a woman is about to enter the women's restroom. Do you stop and ask her for her birth certificate? Does she have it? Do you carry yours to every bathroom? Step 2: Someone files a lawsuit saying this unenforceable law violates their civil rights. Okay. Let the courts decide. But before they can, the President of the United States, in his copious free time, having no other crisis to deal with, pronounces that everyone must be allowed to use whichever bathroom they choose. By what authority? Actually, he uses the authority of a thug. Follow my orders or I'll cut off all federal funding to your state. That's thugish. I has no legal basis. Now do you see the absurdity of it all?

If by man you mistakenly mean transgender woman I would probably allow her to go pee since that is the only thing transgender women have been doing in bathrooms for the decade that 18 states have allowed it.
If what you mean is an actual man then I would politely ask him if he had entered the wrong bathroom. I imagine he would probably say "oh I did" since statistically speaking your daughter is more likely to be assaulted by a family member, clergy member or educator than a random stranger in a public restroom. In fact instances of that are almost non existent and have never been a result of a man pretending to be transgender. So I would be much more likely to assume that he was a janitor, that he was checking on his elderly mother or young daughter or that it was an early stage trans woman who did not yet get to enjoy passing privilege than that it was a rapist pretending to be a Trans woman to pray on my daughter.
In fact I would probably be finding myself wondering how it is that a country full of sane, rational people with the whole internet at their fingertips kept drawing the conclusion that the statistically least likely thing was going to happen. It would be like not swimming in the ocean for fear of sharks or flying in a plane for fear of crashing.
Of course I'm an educated person capable of making my own decisions and capable of teaching my children love and understanding while also teaching them to be aware of their surroundings. Maybe that's odd.

Ask yourself this: do you really mean a man, or do you mean anyone who you think looks like a man? Women are being assaulted every day now because some overprotective men *think* that these women look like men. Are you really making women's bathrooms safe from men when you are the man who beats up a woman just because you *thought* she looked like a man?
