I also agree, in general, American Moslems are probably the most tolerable and most integrated of all Western Moslems. I think America's sense of nationalism and integration has gone a long way in that, as compared to Europe's surrender to its immigration wave from Africa and the Middle East.
With that said, Detroit is a hell hole of Moslem intolerance. The fact that the police do nothing to reign in Moslem violence does not help the matter.
As far as the Islamic world is concerned, there is a pattern there of either all out extremism or among the vast populace, silent consent for what the terrorists are doing.
I can’t dispute your point about Detroit.
