We have a basic conflict with our schools and our thought processes. The nonsense doctrine is put forward that we must include all young people and we must not have any of them lost to the school system. So what does a teacher or school official do when confronted by the fact that there are kids that are mean, unreasonable, and with savage desires and actions? Dare we to toss the punk out on his or her ear? That would force us to admit that the system is not for everyone. We wait a bit until we start tossing kids out of the educational system by things like the price of college etc..
The second point is that we are so anti violence that kids can not defend against bullies very well or in some cases the victims have an almost robotic programming that will not allow them to deal with a bully. Frankly the best way to deal with a bully is to beat them down so badly that they will quake in fear over the thought of ever offending you again. If they are stronger use tactics, weapons, or several strong friends to kick them half to death. On a junior high campus the message spreads really quickly that bullies get hurt bad in ways for which the suffering will tend to last them for decades.
