You have got to be fucking kidding us:

Nearly two-thirds of Americans believe the federal government had warnings about 9/11 but decided to ignore them, a national survey found. And that’s not the only conspiracy theory with a huge number of true believers in the United States. The poll found that more than one out of three Americans believe Washington is concealing the truth about UFOs and the Kennedy assassination – and most everyone is sure the rise in gas prices is one vast oil-industry conspiracy. Sixty-two percent of those polled thought it was “very likely” or “somewhat likely” that federal officials turned a blind eye to specific warnings of the 2001 attacks on the World Trade Center and Pentagon. Only 30 percent said the 9/11 theory was “not likely,” according to the Scripps Howard/Ohio University poll.

Idiots.
Conspiracy theories are parasitic on sound epistemic and deliberative norms. Persuasive conspiracies that have gotten some social traction are marks of cultural and deliberative disintegration, a particularly dangerous detour in Burke’s guilt-purification-redemption cycle. The pomo defense of conspiracy theories – that they’re disruptive intrusions into hegemonic discourse that work by “just airing some questions” – was already untenable theoretically. Following Burke, persuasion simply doesn’t work that way. It works through a relatively well-described process of attempted identification and then – when that identification fails – either scapegoating or self-mortification. Persuasion through disidentification is a contradiction in terms.
Now that one of the dumbest conspiracy discourses ever is the hegemonic discourse, the already untenable defense of conspiracy theorization has becomes empirically incoherent.
