This Modern World on dangerous reference books

I don't have anything new to say on the topic of almanacs, but I wanted to link to This Modern World's take on this absurdity.

It makes me wonder - by dignifying the suspicion about almanacs etc. with a response, am I playing into the hands of those who cast these aspersions? It's hard to know, but I think that one of the few defences against the Bush Administration's Big Lie tactic is for many people to challenge the falsehood early, loudly and unambiguously.
