Not sure why you want so much to talk about Arab states, but anyway, just in the spirit of conversation- personally I've observed that ME countries, with all their troubles, seem to be much more religiously (and probably ethnically) diverse than European countries. I come from an extremely homogeneous country from both aspects, it's funny when a country made exclusively by white Catholics talks about the intolerance of places where three or four different religions and minorities have coexisted for hundreds of years.
