My friends will also think, I imagine, of the crazed popularity of seven-eleven denial, especially in America.

Er, didn't you mean nine-eleven? I'm not sure if there are many people denying the existence of the popular convenience stores, although they may very well believe they're controlled by Judo-Bolsheviks and Masons.

As for the rest, yes... There is a good reading about "Vedan science" promoted by Indian nationalists, in the articles concerned with the Sokal Affair.
I do agree with lots of criticism of Western many-sided imperialism and I appreciate interesting insights which were discovered when not only the findings but also the very methods of social research were questioned. But most of the movement went overboard now, the authority (be it the most innocent and most valid, well-grounded scientifical authority of purely academic character) is questioned for the sake of questioning, and for no other reason at all.
The saddest thing is the mind-blowing guilibility of the most vocal critics of this kind, when it comes to some crackpot theories, dear to their hearts.
