I'm Muslim, and I think Muslim extremists are batshit crazy.
But anyway, I doubt that wars, genocide, etc. would really be the kind of think requested by any sort of god. Would any sort of god (who, in fact, according to all religions, wants humans to thrive and live peaceful lives) want the Crusades? The wars in the Middle East? It really amazes (and kind of scares me) me how some people want awful things to happen "in the name of God".
