hotd> ... anti-American videos ...
They are anti-american because they make fun of americans? Hm. I don't so. I also think it is remotely funny. People from anywhere will say stupid (and funny) things if you shove a microphone and tv camera in their face, but United Statesians are in fact poor at geography. See for example
National Geographic's surveys, where fewer USians can locate USA on a map than can people in Canada, France, Japan, Mexico and Sweden. (Along with other scary results.)
The reason why people bash the US for no good reason (which I agree happens a lot), is partly that the US is very active in world politics, and for that reason steps on many toes, and partly for the reason mentioned earlier, because of jealousy. That's my view at least.
That many USians are very patriotic and start the tired "but we saved your asses in WW2!" every time someone criticizes the military actions of the US probably doesn't help either.
Speaking of country stereotypes, and keeping on-topic, those Japanese sure are crazy!
