“The human psyche has two great sicknesses: the urge to carry vendetta across generations, and the tendency to fasten group labels on people rather than see them as individuals. Abrahamic religion mixes explosively with (and gives strong sanction to) both. Only the willfully blind could fail to implicate the divisive force of religion in most, if not all, of the violent enmities in the world today. Without a doubt it is the prime aggravator of the Middle East. Those of us who have for years politely concealed our contempt for the dangerous collective delusion of religion need to stand up and speak out. Things are different now. ‘All is changed, changed utterly.”

“My point is not that religion itself is the motivation for wars, murders and terrorist attacks, but that religion is the principal label, and the most dangerous one, by which a "they" as opposed to a "we" can be identified at all.”

“Many of us saw religion as harmless nonsense. Beliefs might lack all supporting evidence but, we thought, if people needed a crutch for consolation, where's the harm? September 11th changed all that.”

“I need to learn not to bend over backwards to be nice to faith-heads. Give these people an inch and they take a league. I think, as I did when I wrote The God Delusion, that the Roman Catholic Church is a disgusting institution, the second most evil religion in the world.”

“It would be intolerant if I advocated the banning of religion, but of course I never have. I merely give robust expression to views about the cosmos and morality with which you happen to disagree. You interpret that as ‘intolerance’ because of the weirdly privileged status of religion, which expects to get a free ride and not have to defend itself. If I wrote a book called The Socialist Delusion or The Monetarist Delusion, you would never use a word like intolerance. But The God Delusion sounds automatically intolerant. Why? What’s the difference? I have a (you might say fanatical) desire for people to use their own minds and make their own choices, based upon publicly available evidence. Religious fanatics want people to switch off their own minds, ignore the evidence, and blindly follow a holy book based upon private ‘revelation’. There is a huge difference.”

“Religion is not the root of all evil, for no one thing is the root of all anything.”

“Though the details differ across the world, no known culture lacks some version of the time-consuming, wealth consuming, hostility provoking rituals, the anti-factual, counter-productive fantasies of religion.”
