I recently viewed an episode of Gangland on The History Channel. This particular show, which documents the rise of the younger members of the Imperial Klan of America (or KKK), really roused my anger. I thought, "How could people be so ignorant and foolish?" Can't they just accept that the United States has always been an ethnically, religiously, and ideologically diverse country?
The dynamics of "violence begets violence" are simple and probably understood by everyone who has ever been in a fight.
