This is a lazy cop-out for people who don't really care to spend any time thinking or looking at evidence. Which might be emblematic of the real problem. Knee-jerk anti-Americanism isn't a bit more sophisticated than knee-jerk pro-Americanism.
What?! Team America: World Police isn't anti-American or pro-American. It is a satirical caricature of the U.S. It's grossly exaggerated, maybe, but it isn't false.
As an American, I'd say it does a great job at lampooning the way America sees itself and how America sees other countries.
Those guys chanting "U-S-A! U-S-A!" at international sporting events? In their hearts, they're singing "America: F--- Yeah!"... or at least some Lee Greenwood.
