I only browsed in the article itself, but my antipathy to conspiricism is independent of both its popularity in any given instance and, even, the correctness or incorrectness of any given conspiracy theory.
I object to conspiracy theory because promulgating it (like throwing the word "fascism" around) tends to deflect from the nature of capitalism and of the fundamental policies of capitalist states. The charge "fascist" against Bush or the charge of administration conspiracy in the case of 9/11 (or of CIA involvement in the assassination of John Kennedy) have the _material_ effect of giving aid and comfort to the Democratic Party and to the arguments of those who claim that capitalism is the best system but is corrupted by bad people in one way or another.
To put it another way, if I held in my hand absolute documentary proof that Bush & Co. had plotted 9/11, I would immediately burn that documentation.
The exposure of the Watergate conspiracy was _one_ of the factors in the steady rout of the left after 1974.
