Well, that's the thing. When it comes down to it, every culture is going to find something about some other culture offensive. That's why different behavioural groups exist to begin with. Like breeds with like, even within a single population, and BEHAVIOUR shouldn't be discounted, but the "scientific" only look at looks most of the time ...
Witness "Abraham" getting fed up with Sumerian polytheism and whatever he thought its bullshit was, and taking his family, friends and slaves along to settle someplace of their own (only with(out?) blackjack and hookers!) Separate them long enough, they develop different dialects, maybe slightly different looks, and eventually, generations upon generations of refusing to breed with one another, oops, their genes no longer quite match up, and Romeo and Juliet spawned a human mule.
