Annals of zealotry

I won't call it "epistemic closure," because I agree that's a term best retired. But if you want an example of the vehement close-mindedness of today's talk-radio-benumbed right, it would be hard to beat Mark Levin's characterization of Jim Manzi (who opposes cap-and-trade or carbon taxes but wants research on geoengineering in case climate change causes serious problems) as a "global warming zealot."
