[+/-] Democrats dominate academia because they are smarter than Republicans

I want to point out a couple of choice excerpts from letters to the editor of today's New York Times. These letters are responding to an article from November 18th, "Republicans Outnumbered in Academia:"

[A] national survey of more than 1,000 academics, shows that Democratic professors outnumber Republicans by at least seven to one in the humanities and social sciences. That ratio is more than twice as lopsided as it was three decades ago, and it seems quite likely to keep increasing...

Here they are:

Academics are trained to reason using logic, to question evidence and to consider and evaluate several possible interpretations of events. All these activities are discouraged and indeed ridiculed by the present Republican leadership.

Similarly,

A successful career in academia, after all, requires willingness to be critical of yourself and to learn from experience, along with a lack of interest in material incentives. All these are antithetical to Republicanism as it has recently come to be.

I think these writers are onto something. Other evidence, albeit circumstantial, abounds. Take a look at the aggregate IQ scores of the Blue states vs Red states. Blue states have a dramatically higher IQ. Or to put it more eloquently:

[Republicans] are stupid. They believe that Saddam Hussein was directly responsible for September 11, 2001. They think corn syrup is food. They believe that there's no such thing as stateless terrorism. They believe that "the left" is responsible for the revolting cesspool of popular culture. They don't believe in evolution.

They think Bush is a godly man.... They believe in one paragraph out of Leviticus, but they ignore the rest of the Bible. They let themselves get scammed over and over by robber barons and religious hucksters. And apparently, although I find this hard to conceive of, they believe that the media is liberal. They're fucking stupid....
