I disagree with Moore's agenda and I know full well that his editing choices are very misleading. Not only that but I realize that others might be influenced by this misleading editing and the obvious appeals to emotion (that is what this "documentary" truly is for, to get people riled up and angered at "Bush's war"). Knowing all that, I am still glad that this film is being watched, as it gives both sides opportunities to discuss the issues and hopefully debunk the myths.
As a side note, I keep hearing mentions of the tape of Bush sitting in the classroom for minutes after an agent whispered something to his ear. I have watched it myself and am wondering: how do people know what that man said to Bush? How do we know he said "the nation is under attack"? And if we don't, why is it so easily accepted as fact? As Bill has said, that man might have said anything, maybe even "A plane has crashed into the WTC."
