I'm impressed with these boys?

Wow, what a major over-reaction! I think having a fight club is a lot better way for these boys to burn off their testosterone than bullying other kids or banging every girl in sight. I could see them getting in trouble for having it on school grounds, but if they were doing it in their own time on their own property, then the school had no business expelling them for it. Chances are the expulsion was for both venues.
