Nah, I'm not cool with a dude entering a bathroom with two underage girls. He should of thought about that a little more before arguing and escalating the situation. If protections are given to men in drag, what stops a pedophile from throwing on a dress and entering a womens bathroom, or gym locker room because he legally can.
Also, anyone who relates Gender identity disorder, a mental illness, to someone being of a certain race doesn't understand the entire issue.
