In February 2002, four years before his book The God Delusion was released in 2006, Richard Dawkins called atheists to arms on TED. Seen here. His talk was first posted by TED in April of 2007. He makes it clear he wants a campaign much like the gays used to gain acceptability in American society. His final sentence was, "let's all stop being so damned respectful." It seems to be working.
