There is a world of differenc ein intent between Moore and Bush. Bush lied and if your argument is that he said what he believed ot be true than he is too stupid to survive, let alone muck with the nation. And muck with it he has.
Both Moore and Bush use rhetoric, but the differenc eis one used it to unleash the fire of destructive war-mongering, to spill blood, destroy lives and leave behind the dead of both sides. The other used it to change the leadertship of a country that was pursuing a distorted and harmful path.
I think these differences should be so blindingly obvious as to need no explication, unless one is addressing a hypnotic subject or a blind person.
