Random thoughts about why this law makes no sense. (Forgive me if some of this has been said before; I'm late to the party and dont really have time/inclination to read this whole thread):
Some women are aroused by women. Are we going to also have separate bathrooms for women who like women? What about for men who like men?
In almost any women's room there are separate stalls, so it's not like anybody's getting naked in front of anybody else. Co-ed bathrooms are becoming the new normal in some places, and I don't hear anybody freaking out about those. Do any of the universities in North Carolina have co-ed bathrooms or is that only a heathenish Northeastern tendency?
And anyway, who is going to enforce this law? Is somebody going to police public bathrooms to weed out those trans people who look pretty convincingly of the gender they identify with? Are all North Carolinians going to have to carry birth certificates everywhere they go?
