One redeeming point of the book, I thought, was Dawkin's spectrum of theistic probability:
[link]I would be a six, and Dawkins is a six. He's only "truly agnostic" regards stuff that has a trivial or nonexistent effect on daily life (fairies, orcs, dragons, etc). Religion obviously has major effects on life and thus deserves rational criticism.
The assumption of a presence that's not provable, observable or effectual is irrational
by definition; the only "truly rational" spots on Dawkin's spectrum are thus 4-6. Regards soundness of judgement and compliance with the observable natural world, 6 is the most rational position. 1-3 and 7 are intrinsically irrational.
