Richard Hofstadter in "The Paranoid Style in American Politics" (1965)wrote that
polarization can entail the belief that the other side is in thrall to a secret conspiracy that is using devious means to obtain control over society. Today's versions might go like this: "Liberals employ their dominance of the media, the universities, and Hollywood to enforce a radically secular agenda"; or, "conservatives, working through the religious Right and the big corporations, conspired with their hired neocon advisers to invade Iraq for the sake of oil."
And to get more adjectival assurance on the issues, Wilson says that the debate:
reflects a mutual revulsion between whole geographical sections of the country, the so-called Red (Republican) states versus the so-called Blue (Democratic) states. As summed up by the distinguished social scientist who writes humor columns under the name of Dave Barry, residents of Red states are "ignorant racist fascist knuckle-dragging Nascar-obsessed cousin-marrying road-kill-eating tobacco-juice-dribbling gun-fondling religious fanatic rednecks," while Blue-state residents are "godless unpatriotic pierced-nose Volvo-driving France-loving leftwing Communist latte-sucking tofu-chomping holistic-wacko neurotic vegan weenie perverts."
And the beat goes on......
