> Are you sure that "idiotarian" is a word?
Insofar as it is used with some regularity, yes.
http://en.wikipedia.org/wiki/Idiotarian
"The term idiotarian was coined by Charles Johnson (webmaster of the Little Green Footballs warblog) on January 5, 2002, in response to a comment on the weblog Instapundit.[1] It is an apparent hybrid of 'idiot' and the '-tarian' ending common to words denoting political ideologies such as libertarian or communitarian."
"The term was initially directed against "idiotic" behavior by figures on both the political left and right,[2] however, it has come to be associated much more strongly with its use by warbloggers, right-leaning, and libertarian bloggers in criticism of the political left. It is sometimes employed in the service of ad hominem rhetorical attacks, but may also be used as a pejorative political slogan or label, and the meaning and usage of the term itself is a subject of politicized debate."
Since anti-evolutionists and other anti-science types are working, knowingly or unknowingly, in the service of the political Left... idiotarian is a good descriptor.

They don't have "Islamofascist," either. The English language evolves rapidly, as do many organisms. Sometimes change is so fast that good records are often not kept. Such is life.
I love the word. I just totally disagree with your conclusion regarding who is in cahoots with the political left. I'd love to see an honest exit poll of Bush vs. Kerry voters and what percentage of each believe in evolution. I'm sure that we would find that a much greater percentage of idiotarians believe in evolution. C'mon now. You know that this is true. And please don't call me a liar because I won't actually go out and do the poll.
A very good explanation but is probably wasted effort. Those of higher and lower IQ have little in common, thought, or understanding.
