Do please watch this video in which Richard Dawkens (The God Delusion) affirms that his sect of Athiesm does indeed reject the idea of an "absolute morality" and is, indeed, rather alarmed by the whole thing.
He then goes on to establish that most people of faith reject many "moral standards" and social norms that are stated in the Bible - slavery and stoning adulterers, for example. He's entirely correct, so far as he goes... Please watch the video, and I'll get into the "however" of it after the jump.
