Actually I thought HLA typing was used to classify all antigens. My knowledge of genetics is quite sketchy and superficial. I haven't taken a gentics class since 1972 or thereabouts.

But I think my point is still valid. It's true, for example, that, say, Pima Indians are more likely to get Type II diabetes than other ethnic groups,but you wouldn't call Pima Indians a "race."

If you look at sub-Saharan Africa, "they" may "all look alike" to the Western eye, but to them the difference between, say, Hutus and Tutsis is enough to kill each other.

The French and Germans look alike to the Western eye, but that didn't stop them form going to war three times in the last sesquicentury.

Race is not the only classification of distinction. Within races there are smaller consanguineous groups and within those there still smaller groups.

True. Emnity between groups need not involve race. Even brothers will kill each other.
