It's not really a generalisation so much as a statement of theological fact (another oxymoron). Look in the Q'uran if you don't believe me. You have to understand that their religion is very, very real to these people. They actually believe this stuff and asking them to tone it down a bit for western consumption is deeply offensive. We look at this religion and ask why they can't have a reformation or an enlightenment, ignoring the uniquely complex structural, historical, economic and sociological reasons that led to our reformation and enlightenment. It's not likely to happen.
