It's not human nature to think you're superior just because of something as random as color or race. That's racism, and I don't think enough people really think about the real definition. Probably one of the most misused terms out there.
But something like what you said about culture or lifestyle or whatever it is, absolutely.
And even with race and ethnicity, I think a lot of what some might sometimes incorrectly view as "racist" is really just pointing out certain stereotypes. But that's just pointing out a stereotype, and many stereotypes do come from somewhere. It doesn't mean you think one race is superior or inferior. It's really weird how people use the word. Someone can say "black people like koolaid." Someone else will say that's racist. But you think about the word... How? In no way does that say anything about how one is superior or inferior to the other.
