It doesn't make it worth it when those new atheists are coming to atheism for the wrong reasons. Dawkins' book wasn't so much a rehash of old arguments, it was a rehash of mostly invalid or deeply flawed arguments. Dawkins is a great biologist and scientist, and I respect him for that. I just don't think he knows what he is talking about when it comes to atheism / philosophy.
There are far more eloquent and philosophically minded atheists who can handle these kinds of things.
