Don't have any current mod points, so I'll just comment: quite so. Disagreeing with someone is not insulting; *insulting* someone is insulting. Dawkins does plenty of the latter. Calling theists "ignorant" is indeed insulting when said theists are well-educated (even in evolution, which I learned as an accepted fact - in Catholic school), and quite well aware of your arguments. For what it's worth, I did read "The God Delusion," and found it trite: his arguments have been answered many times over. Certainly, to an atheist, the answers are not persuasive, but it is foolish to act as though theists are ignorant of the questions posed.
I'm quite sympathetic to the atheistic worldview, but it seems to me that a true atheist would accept the "God Delusion" as as much a product of evolution as tribal instincts, and focus on the advantages of moving past such a delusion, as opposed to characterizing those subject to the "delusion" as ignorant hillbillies. Rationally speaking, that mode of argument only appeals to those who agree with you already. Dawkins is more of an antitheist, or perhaps a "theophobe."
