Most of it is okay, but I disagree with his section on absolute morality. Of course atheists have a sense of right and wrong. It is conditioned into us as children. That doesn't mean there has to be any kind of absolute morality. Morals are whatever their societies want them to be. It's not that radical a concept, and pretty obvious if you look at how the West's morals have changed over the past few centuries (equal rights for all races, women, homosexuality, etc), and even how other societies' morals differ from our own right now.
