Look, we all know that conservatives aren't funny. The question of why they aren't funny, however, is considered only rarely. Here is the shortest answer, which has the added benefit of also being the most correct: they are not funny because they don't understand irony. Irony, misdirection, and the unexpected injury (pratfalls, objects striking someone on the cranium, etc) are the three foundations of comedy. The inability to comprehend irony is the reason that all satire written by modern conservatives is beyond awful, reading like something written by a council of 12 year old boys. Irony does not come naturally to a mind that endorses principles like constitutional literalism, biblical fundamentalism, and a cornucopia of economic theories that are demonstrably untrue.
When we see news items like the Oklahoma Legislature banning AP History courses, we are horrified but we also think it is funny. It is not funny like a whoopee cushion or a pie to the face, of course. It is funny in the sense that right-wingers are too stupid to see the irony in their own actions or how much they resemble the groups and ideologies they identify as enemies. Evangelical Christian fundamentalists do not grasp how similar they are, for example, to Islamic extremists. And right-wing culture warriors and historical revisionists will never be able to see how closely their mission to create their own version of reality mimics Stalinist communism. In an effort to ward off the evils of things like socialism, these dipshits are reaching into the bag of tactics employed by the ultimate in socialist boogeymen.
Isn't that what we always accused the Soviet system of doing – and not without some justification? They censored their media, altered history to suit their ideological preferences, and generally created an alternate version of reality that fit their worldview. I've written before about the Soviet concept of "New Socialist Man," the creation of which required:
A total re-imagining of the world – its history, its culture, its religions, its conflicts, and its societies – was to take place in the framework of a radically ideological system of education with the goal of producing the New Socialist Man. He would understand politics, art, economics, and every other subject from the Correct (i.e. Socialist) perspective. As is the case with every revolution, the Soviets and Mao's China understood that a new culture can only be instituted by destroying the old, and destroying the old can only be accomplished through dictating a new historical reality through re-education.
It was the kind of system that would – to throw out a random hypothetical – ban history textbooks that contained any information contradictory to the official party line. It created "unpersons" who literally ceased to exist, erased from photos and the collective cultural consciousness. It relied on the valid belief that one's conception of reality outside of direct experience is limited by the information available.
Of course, the average Oklahoman is too ignorant of history and reality to understand any of this. To grasp the irony of a situation requires a basic level of awareness that is absent here.
