One step above the Earthbound/Mother series random encounter: The Retro-Newage (rhymes with sewage) Postmodernist Hippie. I imagine some literary critics are annoyed at my throwing Postmodernism into the stew, but as I'll cover in this rant, I'm generally talking about "Postmodernists" who try to apply literary analysis to science and mathematics.
First up: Retro. Newagers just love old crap. I mean "ancient wisdom." They seem to think stuff gets better by the mere fact that it's older. I wonder how long it'll take Plan 9 From Outer Space to become high art, with original reels enthroned next to all the marble statues and Renaissance paintings. When it comes to art, the best stuff tends to come to the surface as time goes on. For every award-winning novel that makes its way into required reading for English classes, there are thousands of cheap, cliche-ridden rags. Though the nostalgia filter isn't so powerful, there are lots of ancient beliefs that don't make it. The most appealing (not necessarily accurate) are the ones that have a habit of surviving. Add on all the psychological defenses the supporters throw in, and you've got a belief that makes testable claims (at least in original format) that allows believers to rationalize away all the failures despite the fact that we can objectively test their truth value.
Next: Postmodern: I'm not a lit person, so be kind about nuances I miss in my quick glossing over. Postmodernism generally involves taking a work of literature and reinterpreting it in some different frame of reference, usually taking into account the time period, the author's circumstances, and so on. I've got no problem with that sort of thing when applied to literature. Newagers, however, seem terribly eager to apply the method to science and demonstrable fact. Their identical cousins, Creationists, are often fond of talking about the racism of Darwin's time, Darwin's alleged racism, and other stuff to try to discredit the modern synthesis of evolution. As if that's going to change the observable evidence or the reasonableness of the inferences we draw from it. One of the archetypal examples I see on fictional TV, and actually once or twice on blogs is the claim that math is too "masculine" for various reasons, and thus wrong. That's the sort of crap that so much woo is built on, and I'm sick of it.
