> All I can say is that there are disciplines and sub-disciplines/fields of study in the humanities that bear all the hallmarks of pseudo-science: extremely small communities, lots of jargon, few journals controlled by everyone in the communities, bouncing articles back and forth between those journals, constantly mixing empirical theses with some philosophical claims ("ideal models"), and so on.

Aren't all of these kind of common to all science fields ? I mean, even in physics, you can see things like string theory... (Though calling it pseudoscience would be too harsh, it's more like 'metaphysics' until we manage to find a way to empirically test it.)
