Teaching children not to hit "under any circumstances" is disgusting. Teaching them not to hit unless they've been hit first is a little better. But really, they should be hitting if at any point they feel threatened. So if someone is being a cruel bully and are acting in a threatening manner, the child should be able to grab the nearest weapon and defend themselves. "Why did you give little billy a concussion?" "He was threatening me" "Perfectly understandable"
