Could be worse...could've been Bill O'Reilly...
You hit the nail pretty square when you pegged Moore for a rabble rouser. That's pretty much his only purpose. In a little touch of defense for ol' lumbering liberal, he does bring up some issues that go ignored. I'm mostly talking about
Bowling which I thought was a good movie, when he wasn't pushing his shaded-truth-views down your throat. That, however, it what happens in Moore films and, really, any director ultimately wants you to see their side of things be it in fiction or non. What I think people forget is that just because something is presented to you in a fashion where you're expected to believe, it doesn't mean you have to. Any politician, salesman, or teacher for that matter is guilty of the same.
9/11... a little too much force. You could have been or followed any liberal thinking person at that time to figure out what that movie was about. On top of that, Moore truly and inexaustably pressed the leftist agenda. That was pretty shameless self promotion as the social conscious of the left for Mikey. I used to think he got a bad rap until that, and now he's been off in the wings being not-so loud mouthed after the sentiment of the coutry was predominantly right thinking for awhile. I expect to hear a lot more out of him shortly.
