James I. Nienhuis is a young-earth creationist blogger (Dancing from Genesis), who not only takes the Bible entirely literally, but also assumes a literal interpretation of Plato’s description of Atlantis in Timaeus and Critias (reinterpreted, of course, to avoid any potential conflict with the Bible). Thus are the results of failing to understand how truth and evidence works.
Nienhuis does admit the existence of the last Ice Age, but claims that it ended circa 1500 BCE. Somehow that observation also disproves global warming (most of the claims are covered in his book Ice Age Civilizations, which is, needless to say, not particularly fact based). He has also tried to show that every god outside of the Judeo-Christian mythology is a descendant of Noah, and his discussions of politics borrow the talking points straight from the WND. (Admittedly, this entry is more or less a paraphrase of this).
Diagnosis: While not a particularly unusual type of denialist – and not, in the grand scheme of things particularly significant – Nienhuis is a rather mindnumbing example of how someone can be fractally wrong on absolutely every single issue as a result of combining fundamentalist religion with ignorance.
For a similar phenomenon, you can try to search up Greg Nikolettos’s youtube videos, though Nikolettos doesn’t really deserve a separate entry.
