The way I see it, anybody who seriously listens to or cares about Dawkins turns into an /r/atheism user (or one of those "new atheists" that Roundy and Thork are talking about), and the people who hate him end up having a horribly twisted image of atheism in general. I don't really have anything against the guy, but I can't help but think that he's a horrible influence.
In the end though, if Dawkins didn't exist, there would be someone else people would think of as a spokesperson of the "movement". He's a product of religious controversy in America, and purely exists to fuel that controversy. There's a reason there isn't a Dawkins or a need for one in secular countries.
