Anybody who thinks in western civilization violence does not exist for the sake of violence has been in the disciplined world of the military for way to long. Detroit devils night would be a good example. The assertion that people don't engage in violence for no reason other than political is a ludicrous as people rioting when their team wins! Maybe that isn't war, or warfare, or diplomacy, but the assertion appeared to be that people don't engage in violence for acts other than those. To use a word from a previous poster that would be ludicrous.
