Why not believe his statement that he has no desire to support Mr Craigs self promotion?

It just goes to show that the issue won't be resolved by logic (arguing logically about religion, which is the epitome of irrationality, seems doomed from the start anyway).

My main gripe with Dawkins has actually always been that he spends too much time arguing with senseless counterarguments. I wish the evolutionary biologists would rather invest more energy into developing more insights, rather than arguing the same old tired arguments of their enemies again and again.

Edit: for what it's worth, I would actually be interested in what arguments Mr Craig would like to present. I checked his web site, but an article about "The God Delusion" that I found was behind a paywall (or at least "become a member wall").
