1. Religion = Bad
All religions are both irrational and intolerant, and they all have a natural tendency toward totalitarianism. All religions are, therefore, ultimately incompatible with humanist values, with liberal democracy, and with the ideals of individual liberty and human equality. At most, Islam is simply a worst case scenario, but the negative characteristics of Islam are shared with all religions, if to a lesser extent.
Proponents: Atheists, Agnostics, Secular Humanists [This position was formerly that of most of the Left, but nowadays leftists are among the most loyal apologists for Islam.]
2. "Islam is retarded."
Islam is uniquely irrational and intolerant, and its tendency toward totalitarianism sets it apart from other religions. Christianity, on the other hand, is especially compatible with, and in fact helped to give rise to, humanism, democracy and the ideals of equality and liberty.
Proponents: Geert Wilders, Sarah Palin, etc.
3. The Three Impostors theory
All monotheistic religions have their origins in totalitarian designs. In particular, Moses, Jesus & Mohammad were "grand masters of the art of trickery" whose sole motivation was the desire "to oblige the people to submit to them." The teachings of these "Three Impostors" have been cynically perpetuated down through the ages by "the ambitious" who used religion to accomplish "the propagation and perpetuity of their laws, as well as the culture of such ceremonies and fanaticism as they deemed proper to establish." [Quotes taken from infidels.org.]
Proponents: Variously ascribed to Friederich II, Averroes, Michael Servetus, Machiavelli, Rabelais, Erasmus, Milton, Giordano Bruno, Boccaccio, Gassendi, Spinoza, etc. The overall argument is similar to those found in the Enlightenment critiques of Christianity penned by Voltaire, Hume, Paine and Gibbon, and also to the writings of contemporary Egyptologist and historian of religion Jan Assmann.
4. The Evil Twins theory
As tempting as it is to classify the monotheisms together as above, it seems, at least to me, to be an outrage against common decency to lump the Jews together in this way with those who have expended so much energy to exterminate them. And I think there is also a need to give far greater weight to the practice of intolerance than to merely theorizing about it. We should look first to the historical record, according to which there can be no doubt that Christianity and Islam form their own aberrant subset of violently intolerant religions - religions that leave a bloody trail of smoking destruction everywhere they go. Having established this category on the basis of objective facts, we can then look to the "teachings", such as they are, of these Evil Twins, to better understand their behavior.
Proponents: Yours Truly
5. What is wrong with Islam? Nothing. And you are a vile bigot for even asking.
Islam is the Religion of Peace. It is not a mosque and it is not at Ground Zero. Arbeit macht frei. We will be greeted as liberators. The public was never in danger. It's morning again in America. We are the ones we have been waiting for. The smoking gun in the form of a mushroom cloud. Universal home ownership. With the Big Mind Process, a genuine kensho can occur in about an hour—seriously. Remember the Maine. We believe the products we make are not injurious to health. We have always been at war with Eastasia. Land Bread Peace.
Proponents: Karen Armstrong, Barack Obama, etc.
