The thing you have to remember about Moore is that he never outright LIES, but rather creatively edits his work and presents it in such a way that it is very misleading and borderline slander. His lawyers are very good at what they do.
His hipocracy (sp?) is also quite evident in his daily life, as he presents himself as the blue collar guy from Michigan, while living in the upper west side of Manhattan in an apartment he owns worth over $1 million.
The worst part about all of his misleading information and creative editing is that it actually takes credence away from his work. In Bowling for Columbine he could have made a very damning film about America's facination with firearms, and especially handguns, WITHOUT DOCTORING THE FILM. There are plenty of real issues and facts that can make the point that handguns increase the murder rate of any city or state or what have you.
Instead he chose to stage scenes, edit Charlton Heston's speeches together to get his desired effect, and also outright lie, or I should say strong insinuate a lie, about the missile factory in Columbine. The truth is just not damning anough for Michael Moore and the more the serves his agenda instead of the actual TRUTH the more it hurts his credibility in the eyes of those who don't think exactly the way that he does. So in essence, all Michael Moore acheives is a form of intellectual masturbation.
