> racism, something that's blatant all over America (some might say, it's what defines America)
A number of replies on this, but some have, I think, understated the issue.
In all honestly, I would say the U.S. is just about the least racist country on earth. If racism is not seen to be a problem elsewhere, then it's largely because of ethnic homogeneity, not lack of racism.
EDIT: It looks like I'm being misinterpreted here. Obviously, there is racism in the U.S. It is a huge problem. We all know this.
But the reason it might seem to be a larger problem than elsewhere is because of our unusually ethnically diverse population, not because of unusually high levels of racism. Also things like our incarceration rate -- the highest in the world, by far.
To a large extent, the political boundaries of the world are drawn along ethnic lines. Where this doesn't happen: former colonies in Africa, much of Eastern Europe after the world wars, etc., etc., you often get people killing each other. Look at the Rwandan genocide, or the mess that Yugoslavia turned into when it stopped being just Yugoslavia, or the decades of troubles between India and Pakistan, or any number of other examples, to see the result.
And then note that these kinds of things are not happening in the U.S. -- not to that extent, anyway.
