Why do you go to a show to trash talk a band? Don't waste your money. I hate bros, I hate faux hardcore, this pisses me off.
Edit: I am not trashing the bands and their music, I get mad at the attitudes and consequences that these kids think are associated with it. Be respectful, I'm sick of hearing of stuff like this.
They were supporting Machine Head, so I assume it was some metal bros that weren't too happy with BMTH playing.
Either way, stupid actions all around.
