Huh? You do realize that most of these attacks are not videoed and that the press makes a point of not reporting the race of the attacker?
One of the things that stands out to me is when Van Jones stated that it is overwhelmingly white males who go into schools or other public places and randomly begin shooting strangers, this site went into an uproar. Thus, such a double standard gives me the impression that white advocacy is a strong theme here. The problem is that blacks tend to not want to join a group that practices white advocacy.
