Another thing to consider, is that children aren't born - ethnically aware or racist...They're taught to be. They're not taught from "birth" that people are the same regardless of skin color. Personally? Racism confuses me. I just don't see the need for it. People are - regardless of color - nice, mean, smart, not so smart, tall, short, thin, fat..etc...yes they speak different languages, but they're not any different that someone else. To say - All - ..... are this or that is a very narrow mindset...To expose children, teens and adults to other ethnicities, it has to be done in a way that is made to be unbiased. Difficult in a culture that likes to be homogeneous. Different is not always a good thing. Same is better. But that's not the way it is every where and that's a difficult concept to teach.
I am from a state which is extremely diverse even with it's population verses it's size, and we still have issues between ethnicities...
Also, it's a matter of perspective. In teaching here, many of my kids are very surprised that Korean isn't taught in schools in America. Korea, from my point of view, and what I have observed is very self centric. (Then again, so do I think America is just as self centric)
It seems to have this idea that world revolves around it and is larger than it is, and mind you this is from the comments of Elementary, Middle and High School kids I have taught and some of the adults I have spoken to. They don't seem completely aware of the countries around them. That is to say, that they're taught about the countries around them, but not taught the cultures of the other countries per say. That being said, it's not easy to touch on over 200 countries, languages and cultures.
Teaching a sense of global community requires a basic re-writing of the worlds - (and I say worlds) countries, curriculum as far as how the view of being diverse is a good quality. Believing different things, is a good quality, learning acceptance, forgiveness in place of attacking each other. Sharing the wealth rather than hoarding it.
The very root of the philosophies have to change between cultures and governments and countries. And that is a feat that I do not think that our current level of awareness is willing to relinquish and change to make the world a more globally connected place where people are treated equally regardless of skin or gender.
And that's my .02 cents worth -
