I think someone would have to be crazy to not believe that this movie is political. And equally crazy to believe that Moore doesn't have an agenda. Some may agree with his agenda, others not. However, if it's true that he's stretching the truth to promote the agenda, it totally destroys his credibility. Besides, truth is always stranger than fiction. The truth in and of itself would have provided ample fodder for him, so there was no need to go any further than that.
