Time says it better than I could: Shame on You, Mr. Moore! Shame on You!
It’s not so much the message as the delivery, if you want to sway anyone to your point of view. Sure, plenty of people cheer Michael Moore’s antics. Those people already agreed with him. If he intended to influence anyone who was ambivalent, he just added some fuel to the “anti-war protestors are nuts” fire. It’s too bad, because you could make a pretty solid guess that most of the members of the audience agreed with him, just based on the stunned silence that greeted him. Scared of blacklists, much?
