It's comical how many believers offer their opinions of recent books by Richard Dawkins, Daniel Dennett, et. al., without having read them. Obviously they assume that since these books take a less-than-fully-approving approach to the religion issue, they're well within their rights to dismiss them without knowing what they actually say.
I consider Dennett's Breaking The Spell: Religion as a Natural Phenomenon the best of these recent books. Dennett takes great care not to alienate believers: the 'spell' to which the title refers isn't religious belief itself, just the unspoken social prohibition against taking an objective look at religion. Throughout the book, he makes it plain that people's actual beliefs are irrelevant to the religion debate. What he's discussing is the development of the current dynamic of religion in society, and the self-perpetuating social construct that modern religion has become.
And for his efforts, Dennett has been dismissed as a cynical killjoy. Believers routinely denigrate his fascinating work as an "attack on religion," without having even the least familiarity with his actual thesis.
