It's pretty interesting in a sociological sort of way how this "denialism" works: a lot of folks that seem to think Glenn Beck is a Deep Thinker also seem to be creationists and/or global warming deniers and/or say AIDS and HIV are unconnected. A very strong anti-intellectual, anti-"elitist" thread runs through all of that.
The fundy faction on Texas's State Board of Education more or less embraces all of that, as far as I can tell. Oh, and also in the news: a couple of the very fundy ones got voted out on Tuesday.
