As many know, I am of the opinion that both theists and non-theists are responsible for serious crimes against humanity. This particular statement struck me as an eloquent explanation of the real reason why fanaticism causes such behavior.One reason why I feel so strongly that we wouldn't be better off without religion is that, by no means is all religion fundamentalist, extreme, exclusive, and damaging. At its best, it is something modest, inspiring, and sustaining. The modern division, to my mind, should be seen as that between those full of certainty, who scorn the beliefs of others and have a dogma of their own that allows no real debate, and those who are occasionally full of doubt, but who are tolerant and who are respectful of other people's views. That division is by no means between the religious and the secular. The Crusades, Islamic, Christian, and Jewish fundamentalism, Facism, and Communism are all the results of total certainty. For me, the moderates, religious or not, are the ones who need to unite. And those moderates within the religious world have much to give, to teach, and yes, also to learn.

So the question for debate: Is it unquestioned belief in general, or religious belief in particular that causes the negative behaviors caused by fanaticism?
