Islam needs a Martin Luther(reformer) and Jesus(Truth) too!Nearly all the really bloodthirsty stuff in the Bible is in the Old Testament, something conveniently ignored by apologists for the bloodthirsty and otherwise retrograde aspects of Islam. Not always smoothly, the West has managed to progress with Christian religion and an overall tolerance of other religions.
So the proof of the pudding is in the eating: Christian religious nuts are a small minority, and Christianity is hardly ever blamed for social or political problems in the West, while Islamic radicals are such a large minority, perhaps even a majority of Moslems in some nations, that, ipso facto, Islam is a problem just by the way it is practised by its followers.
