He has been successful in giving Science a terrible name, he has portrayed Science as the ultimate truth and created his own little cult of followers (fundamentalists atheists). In no way, he can be compared to Carl Sagan, an honorable man who managed to get millions of young people to see Science as an interesting subject.
The fact that we are discussing "what is wrong with Richard Dawkins?" says a lot about that it may be something wrong with his tactics. But we are not alone. Even the Royal Society has noticed that people like Dawkins are giving the wrong impression about Science:
"If we give the impression that science is hostile to even mainstream religion, it will be more difficult to combat the kinds of anti-science sentiments that are really important," Martin Rees head of the Royal Society

So I am not the only one who thinks that Dawkins is giving Science a bad name and is creating the opposite effect.
Well I think the problem is that people like Dawkins and (from this thread) skeptigirl are completely right: logically speaking, there is absolutely no difference between religion and any other form of woo like astrology and homeopathy. On the other hand, it's no use denying that people don't think about religion the same way; given a theist and an astrology believer, the theist is probably much, much more attached to his religion than the astrology believer is to astrology. And, therefore, the theist is likely to get more offended when you question is religion than the astrologer is when you question astrology.
So there's sort of a dichotomy ... do you treat religion exactly like any other woo belief, or don't you? On the one hand, treating it like any other woo belief is more intellectually honest, because it is a woo belief. On the other hand, treating it differently from other beliefs is sort of dishonest (because intellectually speaking, it isn't any different), but is probably more likely to get your views seriously considered, because you're avoiding attacking the beliefs that your audience hold closest to its collective heart, and this is obviously a boon to skeptics. If you tell somebody, "homeopathy is false," you're more likely to convince them than if you say, "homeopathy is false, and by the way your most cherished belief around which you base much of your life is a childish lie."
So, there's a question; do you do what's most intellectually honest, or do you do what's more likely to get converts to your way of thinking (in most areas)? Dawkins, Hitchens, etc. al have obviously opted for the first option; I tend towards the second. Either one is open to criticism.
I found your citation to be a little questionable, btw, because although Rees did say that, he wasn't explicitly criticizing Dawkins for it, based on your link.
