Arguably the successor of Kent Hovind to the title of mackerel baron of the biblical creationist movement, Ken Ham is the well-known founder of Answers in Genesis (a pertinent description of which is found here, and also here). He originally hails from Australia (where all the kangaroos apparently floated after the Ark stranded in Turkey; see here). He is very diligent and shovels a lot of shit every day, completely delusional and utterly unable to distinguish fact from fantasy.
Also generally recognized as a human spambot that generates sentences with no regard for their truth or justification, their cogency with previous statements or any conceivable rules for good critical thinking, but in a completely predictable manner, such as in this case where the input cue is the term “atheist”. See this, and also this.
His favorite debate technique is a version of the Gish gallop known as the “Ham Hightail” which consists of jumping from point to point, ignoring all contrary evidence, and quoting the Bible whenever proof is required. Since the purpose is to retain the hold of those who already believe creationism is backed by science, if all else fails the hightail prescribes the “different worldviews” (i.e. atheist vs. moral) gambit.
Ken Ham and AIG also run the world-famous creation museum in Kentucky, a monument to ignorance, fundamentalism and denialism. The main purpose of the museum is to promote the idea that humans and dinosaurs coexisted peacefully before the Flood. The T Rex ate coconuts, and the reason animals ended up on different continents was that plate tectonics happened really, really fast after the flood. It “says quite a lot about Ham and his followers that they find a 4.5-billion-year-old Earth wildly implausible next to the notion of a tyrannosaur calmly grazing in a meadow.” Ken Ham and AiG seem to have failed to realize that the Flintstones is not a documentary. This is also pertinent, as is this.
Absolutely clueless and ignorant about science, Ham is also fond of dismissing any evidence on the grounds that the presenter is (purportedly) an atheist – a standard conspiracy theory trick, really.
He does, however, realize that Dembski’s old earth, intelligent design creationism is “bizarre", though not obviously for the right reasons.
Ham is also constantly complaining that scientists are unwilling to take him seriously. Go figure (He really, really doesn’t get it, though).
A couple of other examples: Ken Ham (feebly) claims that his Noah’s Ark claims are misrepresented.
Ken Ham on the Virginia Tech shootings (predictably).
Ken Ham on Tiktaalik.
Ken Ham applies double standards for Jesus.
Ken Ham fails to stay classy.
Ken Ham goes insane.
Oh, and Hitler.
And so on, and so forth. You get the gist.
Diagnosis: A clod, crackpot and (unintentional) con artist; seriously deluded and influential in the manner of Kent Hovind; Ken Ham is perhaps the leading advocate of traditional creationism and naïve biblical literalism. A threat to reason, sanity, intelligence and rationality everywhere.
