Well, George, I think he seemed mixed partly because he is, and partly because D.J. seemed to be pushing him to either join Dawkins or criticise him, and he didn’t seem inclined to do either, at least for the POI audience. I think he basically agree with Dawkins’ positions personally but feels, as obviously many of us do, that the confrontational, arrogant style Dawkins often uses is not the most effective way to communicate science or forward a scientifically-based social agenda. He was fairly clear that if you insult people you close their minds to what you’re saying, like when you use the word “delusion” in the title of your book. But, since he’s basically on the same side as Dawkins, I think he was reluctant to be too critical of him.
Some people seem to have trouble with the difference between style and substance. It is often implied that if one eschews Dawkins abrasive style one is pussyfooting/tiptoeing/pandering and so forth rather than speaking truth. I think that’s nonsense. I think communicating truth effectively requires adopting a style that suits the audience, and it is clearly possible to do this without compromising the integrity of the content one is communicating.
