I certainly wouldn't call Moore himself a moron, since propagnandist, fraud or conman are much more accurate pejoratives in this case. I have however heard the colloquialism "Moore-ons" for describing his more rabid fans, since even cursory investigation into Moore's claims will easily invalidate them. I'd especially recommend looking into the timeline behind his first hit Roger and Me, and pay very close attention to his clips of Charlton Heston in Bowling for Columbine. Not only is the "speach" Heston gives cobbled together from multiple clips (his tie and the background keep changing between cuts), but if you look at a wallclock in the background during his interview, you can see the hands jumping back and forth as Moore edits the film to make Heston say what he wants him to. Remember that this is a guy that was fired from Mother Jones magazine for incompetence, then greenmailed them for enough money to finance his first film. He's not even from Flint Michigan, he's from the next town over...
