I dont know, this guy pretends like he is an expert on every thing and though he brings up some valid points I question his sources, he used the internet alot, he used wikipedia in a documentary, what the F***???
It seems like he twists the facts and stretches the truth a bit as well.
He does do a good job of playing to your emotions which is why alot of it seems convincing but to me in the end it seems more like He is upset with the republicans and bush administration.

Just like you cannot take the media for granted you cannot take this guy for granted.
