How the fuck is moshing legal, but smoking pot isn't? One is the epitome of violence, the other is the complete opposite...sit back, relax, spark a nice bowl, and chill...rather than jumping into a circle and swinging all of your limbs. I used to have friends that did it a lot, I went to concerts too, but just to watch or to enjoy the music. They'd come out sweating, bruised, and they'd be all happy about it.
