I think I may be the only person in my class besides the instructor who has ever had a thought outside of enthnocentrism.

That's unfortunate... one of the reasons I like polyglots (and why I tend to get on better with people from continental Europe better than I do with Britons) is because they're usually less culturocentric, which in turn leaves them open to being less ethnocentric.

In any case, with my background in evolutionary psychology, ethnicity barely comes into it - apart from noting the more interesting sociobiological differences which highlight how things the western world (or, in many cases, the US and its retarded cousin, the UK) sees as "normal" are, in fact, also socially derived.
