These threads are casebook studies for "Morton's Demon Syndrome."
I believe you are correct. Most people find nothing to "debate" and the remainder are ill-equipped to discuss the matter at all. That tends to leave the Creationist side of the discussion to the invincibly ignorant (Gore3000), the fantasists (medved), or the deliberately uncommunicative (f.christian). The random post insertion by the remainder are mostly just to state that they are here and not going to be persuaded from their religious views - although why they insist in mixing their faith with science I couldn't say.
