On a personal level, I don't give a shit what girls do when it comes to moshing (hardcore "dancing" or push mosh). We all look retarded doing it.
The problem comes with the girl's personal accountability when moshing. I've noticed that the majority of the time they want to get as violent as the big boys but once they hit hard enough to hurt a little, the girl card comes out super fast. Also, alot of the times there is some idiot boyfriend that gets super hothead when his wilderbeast girlfriend gets knocked around because she decided to do whatever it is she is doing. I've never intentionally hit a girl but it has happened and I've knocked out more boyfriends than I like to remember.
