Ok, i might be a bit biased...
But seriously, I couldn't find one piece of constructive criticism in this one. All I heard was a lot of whining about how unpatriotic Moore is and how bad he is for criticizing the US. Also, according to your reasoning, he shouldn't be allowed to critisize the US, because the US gives him the freedom to critize? What's the fucking use of freedom if you can't even express your thoughts? If freedom means anything, it's the right to tell people what they do not want to hear (Orwell).
I'm not saying Moore can't be critisized (or how the fuck you spell it), but if you do it, do it right. With some facts that actually matter!
