It's all right that there's no real difference except for visuals (skin, face, bones,...).
But I think all this racist stuff is made bigger than it is. The "white" world has all this connected media and everybody knows what's happening elsewhere but are there really that many racists? I'd say it's a small minority, like few percent of white people who are really racists and not just angry about the criminal different-colored people (and there's criminals of each color).
And I wouldn't bet that, talking about percentage (!), less people from other skin colors, be it black, red, yellow, blue, green (whatever Yoshi-color you can think of), are racists. I simply don't know because it's not all across media, in people's heads, etc. but you can't tell me that all other races love every (wo)man in the world. In some regions it may be due to religion instead of skin color but people judge when they see you and don't ask about your religion first.
