Probably the best assessment of Dawkins I’ve read yet:
The God Delusion cannot be understood as a work of scholarship or of effective engagement of a topic. It’s frequently idiotic, and engages in rhetorical misconduct that disqualifies it as a work of intellectual value. Understood as folk scholarship (we might call it folk theology or folk philosophy), it makes perfect sense. The God Delusion isn’t intellectually sound, and it’s not meant to be. Its purpose is to make people feel better about their world-view. I have the impression that it’s effective in that regard.
