Could it be a form of resentment that is being expressed perhaps unconsciously towards the government indoctrination system? After all schools do squash a lot of individuality out of the person in an attempt to unify the masses toward conformity. I think a closer look into the "subject matter/what is taught" of/in the public school systems and it's effects on the psychology of the child should be done. Schools can be a very ruff place on a kid that could lead to this type of stuff especially if some material that is mandated by the government can be shown to be leading to a bad out come. I think these studies need to be made in a most unbiased way possible and feed the info into a super computing AI and see what happens?
Anyway I think a progressive government should do a good study by experts on this matter. Perhaps then we can see something done about it.
