I have not read his book, but I do not really understand how the comments about religion that you mention can actually be rebutted :)
As JtP has already mentioned - for most atheists, the position is clear- on balance, the evidence suggests that the probability of a creator god is very low. On that basis it seems irrational to have faith in such a being, to offer worship etc. That having been said, were a suitably dramatic, uncontravertible evidence of a deity be demonstrated - no true believer i have ever spoken or debated with has ever been able to convince me that they could be persuaded that their faith is misplaced - ie close minded.
