Richard Dawkins shows off his finest fundamentalist form when he attempts to discredit any possible reason an atheist might have to tolerate religion. Dawkins to my mind is no better than the assholes who work the Third Street Promenade in Santa Monica waving their Bibles and spouting off about the evils of homosexuality. [UPDATE: This is worded too strongly. I should have said something like: some of Dawkins's rhetoric is no better than...]
I personally subscribe to a variant of I'm-an-atheist-but-ism #2: people need religion. There is palpable irony in seeing the Great Logician himself trying to refute this argument by saying that it is condescending. Even if it were (I don't think it is), so what? Aren't we supposed to judge the truth of falseness of a proposition by the evidence rather than on whether or not we think someone might be offended? By rejecting this argument on the grounds of political incorrectness Dawkins shows himself to be just as much of a hypocrite as all the other religious fundamentalists.
But the problem runs even deeper than that because not only is Dawkins arguing ab-political-correctness, he is also knocking down a straw man: It is not that people need relgion, it is that they want religion! Some people, to the perennial chagrin of people like Dawkins, simply prefer existence with the sense of purpose that faith can provide (and frankly I can muster a great deal of sympathy for that position if jerks like Dawkins are the role models for the alternative). This is simlpy a fact. People choose religion of their own free will. It is the height of condescension to suppose, as Dawkins does, that choosing religion is ipso facto an unsound decision, and to appoint yourself as the arbiter of what they should have chosen for themselves.
It gets worse still because there are manifest sound reasons why someone might reject science in favor of religion, not least of which is that there are important questions that science cannot answer. Science, being objective by definition, is by its very nature unsuitable for addressing questions of subjective experience. We can tease out, say, all the chemical reactions that occur when one eats a chocolate bar and still have made no progress towards an understanding of what it is like to eat chocolate.
Science is likewise impotent in the face of mystical experience. Scientists tend to write it all off as delusion, but that is unjustifiably facile. Imagine that there were a genetic mutation that made one unable to taste chocolate, a sort of color-blindness for your taste buds. (When I was in my twenties I caught a weird virus that actually made me completely lose my sense of taste for a few days. It was a very distressing experience.) Someone with this mutation would be utterly unable to grasp the subjective experience of eating a chocolate bar, and if there were enough of these people they might suppose that all the folks waxing rapturous over the wonders of chocolate were (no pun intended) nuts.
Although we are making astonishing progress in understanding how the brain works, the mind is still a deeply mysterious phenomenon. Science cannot yet eliminate the possibility that some minds might be in contact with something extra-physical (or even just complex and subtle, but nonetheless real that we do not yet understand), and so to dismiss religion on the grounds that it is a priori untenable is, at best, premature. But, as ever, it's actually much worse than that. There is an elephant in the atheist living room, a question that is both obvious and unanswerable by science. It is this: why am I me? From my point of view there is this very obvious asymmetry in the Universe that the symmetric laws of physics not only cannot account for, but with which they are in fact fundamentally incompatible. The facile answer -- that the situation is symmetric because everyone experiences this -- is not an answer but an evasion. It does not address the question, which is why do I have this particular subjective experience.
I am personally content to let that question remain unanswered and revel in the delicious mysteriousness of it all. But I see no rational reason for passing judgement on those who might choose to do otherwise.
