Am I out of line observing that the dumber a group of people is, the more violent they are?
Of course, at some point, stupidity becomes self-defeating. We can be thankful, for example, that baboons aren’t smart enough to figure out how to manipulate knives, guns and bombs.
Not at all. While it's true that many Muslims are peaceful, the religion attracts the most violent and stupid of males. Killing innocent people i.e. infidels and enslaving and sexually abusing women is permitted. In fact, pretty much encouraged. ISIS proves that every day.
