No, I also think these guys (always guys..) get a bit too much credit. Though how much of that is the media's fault I don't know. "Remember in in 2006 when Dawkins invented atheism!" I honestly don't remember much of the god delusion. I read it once and gave it away
Sounds like similar to your situation I had read other books on the philosophical arguments before, and this was more reinforcing than anything. Heck, Plato's Euthypro is a equally effective/persuasive. I don't know if these guys really convinced anyone. At least not of atheism. That self-important know-it-alls are awful to be around they have done a good job.. Hitchens and Harris I got the sense were saying the same thing, so I never really got much into their writings, as I didn't quite see the point rehashing it. Not being familiar with it it's interesting hearing your view of Hitchens
If anything I think Selfish gene and Mount improbably were the more interesting things I read from dawkins. Actually teaches something and helps understand evolution.
