Yes, it’s a separate issue, but note that even in the article which you say you have read, Denton clearly comes out as an evolutionist. He presumes that evolution really happened, and differs with some people only over how it happened. So even if your critique of Denton’s account of evolutionary causality should prove to be correct, you still need to retract your claim that he is a creationist – or admit that you are using a definition of “creationist” that is not in line with the common usage for the past 100 years, and formally state your own definition so that everyone can see it.
