Well, they're rhetoric argues we should completely eliminate priors. Since that's impossible (in fact incoherent) in practice they wind up making an exception for priors that look as little like priors as possible.
This list falls into the failure mode I've seen a lot of among "skeptics" attempting to make a collection of "irrational" beliefs. Namely, they have no theory of what it means for something to be "irrational" so they fall back on a combination of absurdity heuristic and the belief's social status.
