The world would be a pretty nice place without Islam
And without most organized religions in general for sure. But if we factored out Islamic fanaticism and Islamic repression of women and perpetuation of ignorance worldwide, we would have probably the most peaceful world order in human history. Sure there are some festering local problems between and within various nations, but the Commies are all but gone. Dictators and Monarchs are way out of style. Everyone's going the way of democracy and capitalism. Good times. Kind of like the way we felt in the '90s when we pretended the Islamic cancer would never hit us over here.
