On BHtv? Who was the theist?
I do agree that Ponnuru and Pinkerton wouldn't be interesting, though. (I don't know Bacevich). If Eliezer does debate a theist, I'd rather it be someone with a well-thought-out position to dismantle, such as William Lane Craig, whom I believe Eliezer has already expressed an interest in debating.
Bloggingheads.tv can't exactly call up, say, the President of France and get him to do a diavlog, but they have some street cred with mid-rank celebrities and academics. With that in mind, how would you fill in this blank?
"I would really love to see a diavlog between Yudkowsky and ____________."
