Very interesting. The tension I was talking about isn't actually the not doing it-doing it wrong tension; it's more the problem of being too essentialist, e.g., at one point in the Anita Blake series, when Anita, part-Mexican and VERY assimilated into European-mainstream US culture, is presented as the good guy, while (apparently - I read this on tvtropes a while back, having only read 1 Hamilton book) a much less-assimilated Mexican woman serves as the bad guy. Or in Twilight: of course Native Americans are werewolves, because "they" are in touch with their, um, what, wild side? Inclusion success, cultural sensitivity FAIL.

That make more sense?
