Why are Muslims more violent and criminal?
Have friends who would start screaming 'RACISM!!!' at the very question(doesn't bother them when you point out islam is a religion and social system, not a race); mostly they want to make excuses or ignore the simple and unpleasant fact that a lot of people in the religion in question, well, this fits. Exactly.
I seriously fear for muslims who don't buy into this, who are moving/have moved beyond the "Thus it is written, follow or else" mindset, and I don't doubt they're scared as hell of the, call them 'traditionals', too.
