There's some truth in that. But the problem is there are no real authority figures in Islam. Or rather, there are hundreds and thousands of them, all interpreting the Koran's demands as the verbatim word of God. No Catholic priest is going to call for the slaughter of Jews, say, or infidels, because he'd be fired by his Bishop. But you gets lots of Immans doing that. Even in Canada, since almost all Imams are from the middle east, we get nasty antisemitic sermons from many mosques.
Well, not all of it. There's Texas and Kansas and other bible belt states. But I would wager you'd way rather like in Kansas than Cairo, and triply so if you were gay or a woman or a Jew.
