I still say, allow fighting in schools again, allow kids to ball up their fists and duke it out.
I am tired of all the folks who say "Violence isn't the answer, violence solves nothing, booo hooo hooo hooo, whaaa whaaa, etc..." Humans by nature are a violent, conquering, species. We very much have a pack mentality, with that pack mentality comes the need to sort out who the leaders are. Historically, this happens around the age of jr. high school (ages 11-14 or so), this is one of the reasons that most school systems are broken into elementary, Jr High, and High schools. It separates out kids at the times they are most violent (and sexually curious, but that is for a different post), it protects the 10 and under crowd from those who are just starting to determine their pecking order, and protects the 11-14 crowd from the pubescent adults.
Kids need to fight, fighting makes us stronger, both mentally and physically.
