Some random thoughts after viewing:
Ray Comfort doesn't understand evolution - this is clear from his failure to engage in the basic concepts. He says he doesn't believe evolution is true (elsewhere he repeatedly describes it as "a fairy tale for grownups"), but if he doesn't understand it he's attacking a straw man - whatever he thinks evolution is, rather than what it actually is.
Given what he's said (and published), this isn't surprising, but it raises an interesting parallel with his own reasons for believing in God. During his discussion with Thunderf00t he mentioned that there was much in the Bible that he didn't understand until he accepted Jesus Christ into his heart as his personal Saviour. Relative to this he's previously stated that the evidence for the existence of God is available to everyone - all they need to do is do as he did: open their hearts to the Lord.
Atheists who have honestly tried this route, without the promised revelation, are told they're obviously doing it wrong. This is a self-fulfilling/defeating prophecy - just like the mediaeval dunking stool used to test witches. Any suspected witch who uses her craft to survive the test is proven guilty and shall not be suffered to live. If she drowns she was clearly innocent - no powers, no witch, and she will be set free to live her life in peace, unmolested. Unfortunately she's already dead.
With most atheists the "you're doing it wrong!" excuse understandably won't wash - it's a "heads I win/tails you lose" kind of reasoning.
Ray's argument in this part of the discussion also seemed equivalent (though with less sophistication) to the reasons given by theologians who object to Richard Dawkins' refutation of "simplistic" theism. A theologian will claim (with suitable snootiness) that the religion Dawkins attacks is "not my religion", and will then expound on some abstruse and intensely personal - but most importantly incomprehensible - faith (usually with profligate redefinition of terms), to the extent that the only other person who could share it is God. PZ Myers satirised this style of theology in his Courtier's Reply.
One could argue, however, that atheistic objections to theology are similar to creationists' simplistic objections to evolution. We complain that the likes of Ray Comfort have no real grasp of the principles of evolution, though they decry it as fictional. Conversely, many a theologian has complained that Richard Dawkins has no real grasp of theology, while at the same time he decries the subject as vacuous.
Of course, there is a crucial difference between the two disciplines. Evolution (by random genetic mutation and natural selection) is documented science that makes predictions (such as what we should expect to find in the fossil record) and so far its principles have not been disproved. In fact, each new discovery whether in genetics, paleontology or any other evolution-related field, has further confirmed evolutionary theory, to the extent that it is as near to a scientific fact as the theory of gravity. Theology, on the other hand, appears to be entirely made up. Theologians of a particular creed may agree on a core set of theological principles, but these result from consensus only, and cannot be falsified. This would be all fine and dandy for literary criticism, but for telling us anything at all about the real world, or the people in it, it's useless.
