I cant see a reason for you getting suspended for getting the crap beaten outta you without throwing a punch. Here, you get 5 days suspension whether you throw one punch or beat the other guy to a pulp. Doesn't really help too much, all it does is encourage the rage (as they won't get in more trouble, no matter how much they fight after that one swing).
Since our school is so laid-back, I think a side effect is practicality. We don't get too many stupid rules (unless enforced by the school board, i.e. no cell phones) and I for one am QUITE thankful for that.
