I think the school system needs to make up its mind already. Either crack down on bullying so hard that children are not given the opportunity to do it anymore, or enable victims to fight back by not suspending them.
When I was a kid there was one bully who teased me daily for months until finally I snapped and punched him square in the face and screamed bloody murder at him. He never bothered me again, and was not permanently harmed.
Our culture is becoming so wussy. You can't hit anyone without being charged with a crime, when sometimes physical confrontation is highly useful. Not only that, sometimes it is completely justified. Other parts of the world seem to understand this. Humans respond to intrusions placed upon their physical boundaries.
Letting young people experience the full backlash against their bullying quickly sorts them out. But all this hand holding and half-measures are so annoying to witness.
