Papalinton: Dawkins showed more than a modicum of wisdom when he intelligently noted, in paraphrase, "It [a debate] would look good on his CV but not on mine." Why give unwarranted oxygen to an aficionado of implausible supernatural superstition?
VR: Because you went to the bother of attacking that superstition. If spend your energy attacking something, you then have to put your own view and the view you are attacking on a level playing field and follow the argument where it leads. You have to be ready to have it out with the leading advocates of the opposing view. Otherwise, you conducting a one-sided discussion, where only the ideas on your side are considered. You may conclude that the public-debate format in which Craig thrives is a bad format. Fine, find another format.
I have never had a public debate with a Mormon apologist. But, if I wrote a book called The Mormon Delusion, and a Mormon were to reply to my objections on behalf of the LDS, then I would have to be prepared, in some format or other to engage that defender of Mormonism, and if several Mormons were to respond, then I should at least engage the best people on the Mormon side.
If Christians aren't important enough to debate, then they're not important enough to attack. Craig is one of the world's leading defenders of theistic arguments. If your thesis entails that theistic arguments are no good, then you have to respond to advocates of those arguments. From what I can see, Dawkins doesn't even know how to state Craig's Kalam Cosmological Argument, much less refute it.
