I was lent a DVD recently of a debate between Richard Dawkins and John Lennox, both of Oxford University. The subject was Dawkin's book, 'The God Delusion'. To hear two such intelligent men going head to head in the finest example of polite intellectual debate is truly refreshing. John Lennox argues from a convinced Christian worldview that Dawkins' arguments are self-destructive and inconsistent.

Fixed Point Foundation, based in Birmingham, Alabama, has organised other debates of a similar high standard. If you want to know how to answer the agenda of the 'new atheists', then here is a place to start.
