Before I picked up this book, I had heard about it a lot, thrown around as Dawkins' controversial, scathing critique of religion. I expected it to be occasionally cringeworthy and pompous, but hoped it to be generally informative.
Today, when I read the last page of the book, it has already reaffirmed my conviction as an athiest (I would hitherto describe myself as somewhere between an athiest and an agnostic).
If to you ‘The God Delusion' sounds scathing, arrogant and disrespectful, perhaps it's because Dawkins has been brutally honest and remarkably clear about his arguments. He picks out the common arguments in favor of theism and religion, unravels them, and explains why he disagrees with all of them. If that sounds disrespectful, it could probably because he is speaking inconvenient truths that you are not yet ready to hear.
