I mostly remember him from the debate on evolution he did with Bill Nye. Everyone told Nye not to do it, since there was no way Ham was going to debate in good faith. Surprise surprise, Ham did not debate in good faith. Outright said no evidence would change his mind in the middle of the debate, that he would always interpret any evidence in such a way that it fit with what he already decided was the truth. Anyway, all this to say fuck Ken Ham.
