The last time I can recall a a FReeper with a denial of reality this brazen was the late, great "Gore3000" who claimed that most planets had "wildly elliptical orbits" and was taken to the woodshed for it; similarly, he claimed shortly thereafter that "a circle is not an ellipse," and on yet another occasion he claimed that "infrared light" caused sunburn. In every instance he denied he had made the mistakes, which were quoted back to him via hyper-links.
I don't know what causes anti-evolutionaries to engage in this sort of brazen denial of their own behavior, though G3k offered the best clue I've seen: he once wrote that no matter what, he would never admit a mistake to anyone from the "pro-evolution" side of the argument.
Such is the level of intellectual honesty, and scientific knowledge, we so often see from that anti-evolution side.
Let's not forget Gore's assertion that Stephen J. Gould wrote a number of papers lauding the benefits of communism, not offering so much as an "oops" when it was pointed out that the papers that he referenced were written by one "Steven" J. Gould, a completely different person.
