It is not, and nowhere did I ever imply it was. I am merely speaking to the culture that birthed these films that is the topic of discussion, and the culture I was raised in and have the most intimate knowledge/authority to speak on. Of course other countries all across the globe have their own prejudices about outsiders. That is a foregone conclusion. One I explicitly referenced in saying "ugly-Americans." I'm not really sure why remembering that's the case, has any bearing on an American evaluating a problem that Americans face and inflict.I'm not sure this is a uniquely American thing.
If anything, it should be even more reason to condemn the prejudices here. This country built up a mythology about itself as a "city on a hill" as an example for the rest of the world to be better. We're a country of immigrants, whose entire existence is predicated upon the tolerance of and cooperation with all sorts of different people. We should be living up to those lofty ideals instead of betraying them. Human nature is tribalism, but human nature is also one of growth and exploration, and our vices and flaws are not eternal shackles either.
