I want his new book the God Delusion (example chapters from BBC).

Our Western politicians avoid mentioning the R word (religion), and instead characterize their battle as a war against 'terror', as though terror were a kind of spirit or force, with a will and a mind of its own. Or they characterize terrorists as motivated by pure 'evil'. But they are not motivated by evil. However misguided we may think them, they are motivated, like the Christian murderers of abortion doctors, by what they perceive to be righteousness, faithfully pursuing what their religion tells them. They are not psychotic; they are religious idealists who, by their own lights, are rational. They perceive their acts to be good, not because of some warped personal idiosyncrasy, and not because they have been possessed by Satan, but because they have been brought up, from the cradle, to have total and unquestioning faith.

It's about time someone said it. The problem the world really has isn't "Islamofascism", it's the literalist religious beliefs of zealots of any religion.
