Why do schools punish students for defending themselves?

Anonymous
It’s ridiculous. Nobody should ever be punished for self defense. I think schools are too lazy to investigate what happened. If I was a kid in school, and if I was attacked, I’d rather defend myself against the bully and get suspended from the school than end up in the hospital. A school like that’s useless anyway.

There’s no excuse for bullying. It’s not a right or a privilege, etc.
