Uneducated is not the same as stupid. These people are alienated, and by the age of 10 most of them feel that the majority culture doesn't want them, can't use them, and hates them just because of their race. Many of them grow up without a father, or whose father and uncles are in prison, often for severely punished minor offenses. Many others grew up with lead poisoning, which causes a lot of behavioral problems, including poor impulse control, angry outbursts, and violence. They are victims and victimizers. The whole thing is a damned mess.
