There is a sharp difference in the suggested approach towards dealing with religion and religious believers between the "new atheists" like Dawkins, Dennett, Harris and Hitchens, and the more traditional approach of secular humanist academics, who concentrated on developing naturalist philosophy and humanist systems of ethics and morality. Paul Kurtz and the quiet humanist approach of building secular organizations, and forming alliances with moderate, non-evangelical religionists who don't insist on pushing their religious beliefs on others, does not get a lot of attention, especially in an age where only vulgar, in-your-face confrontation makes the news.
Sam Harris's book:"The End Of Faith," did not become a bestseller because he wrote the best argument for atheism and counter-apologetics -- it was because it contained a philosophical defense of the use of torture, said the religious right was leading the U.S. to theocracy - yet declared that this was preferable to Islam, which he described as a "cult of death." And then he threw a curveball at the end of the book, with his friendliness towards Buddhism and embrace of the mystical tradition through meditation. Mixing politics with religion is what really sold the book, and the later works by Dawkins and Hitchens copied that strategy. Notice that Dennett's book during the period of atheist bestsellers: "Breaking the Spell," had the richest content, yet the poorest sales, likely because he avoided politics and inflammatory language.
Specifically, regarding Dawkins's beliefs on whether some people need religion -- a key issue since if nobody needs religion, that means atheists should be evangelical about deconverting all believers:
"I dealt with this in the last chapter of The God Delusion, 'A Much Needed Gap' and also, at more length, in Unweaving the Rainbow. Here I'll make one additional point. Did you notice the patronizing condescension in the quotations I just listed? You and I, of course, are much too intelligent and well educated to need religion. But ordinary people, hoi polloi, the Orwellian proles, the Huxleian Deltas and Epsilon semi-morons, need religion. Well, I want to cultivate more respect for people than that. I suspect that the only reason many cling to religion is that they have been let down by our educational system and don't understand the options on offer. This is certainly true of most people who think they are creationists. They have simply not been taught the alternative. Probably the same is true of the belittling myth that people 'need' religion. On the contrary, I am tempted to say "I believe in people . . ."
http://richarddawkins.net/articles/318Even if he's right that the proposition that some people are somehow wired to be religious or unable to break free from a purpose-driven way of examining the world, is condescending or patronizing -- that doesn't answer whether or not it is true. It's worth noting that Dawkins explains the propagation of ideas and concepts by his Meme Theory of propagation of ideas that he shares with Daniel Dennett. If there are good viral ideas and bad viral ideas (like religious dogma), Meme Theory implies that fighting bad ideas should be done in a similar manner to eradicating diseases. Many neuroscientists in recent years have come to the conclusion that there are more basic underlying reasons why some people are religious, while others outgrow this way of thinking
http://bhascience.blogspot.com/2009/11/religious-brain-pragmatist-brain.html If the differences are more than having our thinking infected with harmful viral memes, then the pragmatic approach would be to back off and let people figure out how to fit their religious worldview to the real world, and only interfere when their dogma is directing them towards harmful actions.
The problem is that atheist evangelists will create more hostility from the religious folks, and make fundamentalists more entrenched in their beliefs. And I agree that atheism doesn't necessarily equal rationalism. But people who are able to unload the traditions they have been taught from an early age are more likely to be rational and pragmatic than those who just follow their traditions without question.
