Is Michael Moore the Rush Limbaugh of the Left?

No intention of seeing Fairenheit 9/11. None. It's not that I don't want to hear what Moore has to say, I just don't build my opinions on a foundation of sand. That Moore bungles facts or plain makes them up has been said so many times that it renders moot whatever point he tries to make. Even his fans admit that his films sidestep the truth, albiet to serve a greater cause. But I prefer a good argument to simply hearing what I already agree with.
