I can try and offer an serious answer to that..
Thanks for that thoughtful and informed piece.
My perception is that the various "Abrahamic" religions that came out of the Middle East and all at least doctrinally trace their roots back to Abraham are all influenced by early Hebrew monotheism in two ways -- the condemnation of idolatry and the idea that God is a jealous deity, not permitting the worship of other gods.
This seems just set to evolve into religious intolerance and sectarianism.
Most of the West has learned the value of religious tolerance, even if it does mean you have to put up with idols and religious symbols all over the place, as a way to keep down sectarian violence. Europe learned this the hard way in years of warfare.
That Islam is not a single "thing" we all know; the secularist Muslims I know from Malaysia and Indonesia are Muslims; they don't doubt the truth of their faith, but they are tolerant anyway as citizens of the world. I ask them if I go to Hell and they tell me Hell is a complicated place and not to worry about it. I ask them what they think of a unified Muslim political state and they say not to worry about it either, that they have no intention of being ruled by Arabs, and that is the only way it could happen.
Still, the teaching that all religions but one's own are false and somehow of the Devil or evil is present and is not denied if one presses it. This we rarely find among Christians nowadays and never have found in most Asian religions, except a few under Christian influence (CaoDaism comes to mind).
And this is the thing I think is behind the trouble. Sectarianism is essentially an arrogant idea and breeds intellectual arrogance. Worse, in some personalities inclined to bigotry (and such people are found everywhere), it leads to justification of outrages. Religions need to go further than just teach tolerance; they need to teach that there is good in other religions, that in our limited human perspective we each see only a small part of what no doubt is a tremendously over-arching truth.
We find this idea dominating in more and more of the world's faiths, except Islam and Jehovah's Witnesses (and of course the pacifism of the latter keeps them out of the headlines). As a result I am pessimistic and worried about Islam.
