I think what Pat McCrory is saying is if you can piss over a 3 foot fence you're a man and if you can't piss in a Coke bottle without missing the hole then you're a woman. See how simple it is? I don't see where the confusion comes from.
That's actually not what he's saying, because a transgender man used to be a woman, and is in the process of getting a dick or already has one. And, a transgender woman is in the process of getting her dick remade into a clit, or has already done so. And, McCrory wants to tell those people to use their former gender's bathroom.
So, maybe until you can figure out what McCrory is or isn't doing, you should stay out of my state's politics.
