I'm pretty sure that it would cause a commotion if a man-dressed-as-woman (or perhaps even "post op" transexual) went into the mens room to pee.
I guess it goes to show: this is the chaos that ensues when you give up on every basic category and rule and set about reinventing them based on the theories of the faculty of Ivy League universities. The ensuing social chaos is predictable, if unfortunate.
Anyway, there are long established rules to fair fights, a universal one is that you don't hit a defensless person who has gone down and is staying down. (Also one-on-one.)
The girls who did this are less than dirt, they behave like jackles or wild dogs.
This assertion that the victim was a crossdresser smells like a plan dumb liberals came up with thinking it would make this conservative-fueled story go away.
