A fat, ugly mocumentary err "documentary" producer from Michigan that uses propaganda to brainwash Americans into thinking their country is the worst place to live on Earth. Michael Moore is liberal, anitAmerican, an opportunist and dishonest. He thinks that most Americans are stupid and will believe the propagandist BS he produces. The irony is that he is a college flunkie and was expelled from a major Michigan University for plaigarism. The man has no credibility whatsoever, but wants us to believe he is a truth detector. Stupid "films" he has produced include Roger and Me, Fahrenheit 911, and Sicko. How ironic, because the man IS a sicko.
