Well, just because I'm "white" or "of european descent" or whatever and most of the people I know happen to be white, that in no way makes us look the same way, think the same way, or even come from the same background, which is what you're inadvertently implying by creating two ethnicities with these same characteristics and then simplifying your question. Even though most of my current friends are from the college I graduated from (and most are Asian and white), we still have very different families, interests, looks, tastes, etcetera. I've never had a visible characteristic that makes me markedly different than other people (which ethnicity can or cannot do depending on your reference), but I still think I'd be okay being quote unquote "different" if my fellow classmates didn't treat my difference as a crutch, excuse, or isolating factor.
