Dissent takes down the fat white man. The article notes, rightly I think, that much of the objection to Moore on the nominal grounds of his factual inaccuracies is politically motivated more than anything else, but argues that Moore's technique lets him down nevertheless:
Some reviewers are put off by Moore's aggressiveness. But what's really shocking is how often his technique fails. Sure, in The Big One, Moore got Knight to admit he employs fourteen year olds in Indonesia, and in Bowling for Columbine, Heston mumbles something about ethnic mixing producing violence in America (though the point isn't very clear). Nonetheless, both interviews illustrate the uselessness of confrontation more than its effectiveness. Heston simply walks away from Moore's pushy questioning; Knight grows aloof. [...]
Often Moore can't get to the upper echelons of a corporation or government. Then he winds up confronting a security worker or desk clerk, as the cameras roll. In The Big One, for instance, he tried to get Payday candy bar company executives to discuss layoffs. Security guards push him out the door, and Moore gets persnickety, challenging and mocking them. And so in the name of confronting the powers that be, Moore winds up annoying underpaid security guards. The point of this, I would assume, was lost on many viewers, not just me.
