The reason I put the word "entertaining" in the previous post is because I do have some reservations about public debate as a venue for the adequate airing of issues. The blogosphere, public debate, and peer reviewed journals all have strengths and weaknesses as loci for dialogue about issues like this.
By the same token, Dawkins' career, and even his previous academic position (1995-2008), the Simonyi Professorship for the Public Understanding of Science, are dedicated to the defense of evolution to the general public. The ordinary complaints about public debate as a setting for the exchange of ideas go by the boards here.
It is quite true that if you have a public debate between Bill Craig and someone who is a good atheist philosopher of religion but who is not at home in the debate setting, you could complain that a debate might unfairly disadvantage the atheist cause. Similarly, a good evolutionary biologist might bomb in a debate with Duane Gish, and that this might tell us little about the credibility of evolution.
But Dawkins writes for the public, not only to accept evolution in full, but also to reject belief in the existence of God. He is an excellent public speaker. So he is not in a position to use what would ordinarily be the best arguments against debating someone like Craig or Meyer.
To make a career of making the case for atheistic evolution to the general public, and then to hide behind academic snobbery when challenged to a debate by academically qualified opponents, is trying to have your cake and eat it too.
