R. Slifkin states on his blog that I refused to debate him and speculates on reasons for the refusal:
So why did he refuse? I think that his refusal is for several reasons. One reason is that, especially when dealing with complicated topics, it is always much easier to throw out a list of objections to one's opponent's view than to subject one's own view to objections. Another reason is that he probably really hasn't thought very much about his own model in the first place, and how it addresses the available evidence.This is not true. I openly accept R. Slifkin's challenge to debate what he calls my model provided that R. Slifkin accepts my prior challenge to debate his evolution model using rational arguments. Since my challenge was issued first -- in response to R. Slifkin's model presented in his books -- I insist that we start with his model in an intellectually respectful, moderated, neutral, public forum.
