Here is the story, as far as I can trace it, of Chomsky's effort to "minimize" or "deny" the harvest of the Khmer Rouge. It will be seen that the phony "credibility" of the charge against him derives from his lack of gullibility about the American mass killings in Indochina (routinely euphemized or concealed by large sections of the domestic intelligentsia). From this arises the idea that Chomsky might have said such things; was the sort of person who could decline to criticize "the other side"; was a well-known political extremist. Couple this with the slothful ease of the accusation, the reluctance of certain authors to prove they are not unpatriotic dupes, and you have a scapegoat in the making.
