I would agree that the differences between the 'races' of humans are not as clear, distinct and non-overlapping as the differences between non-mating species.

Consider the differences between fat people and thin people. For many of us, it's not clear which group we are in. My doctor would probably call me 'fat'. I would differ, though I would grant that I am no longer thin.

What is so dang hard about the notion of overlapping groups, such that for the bulk in the middle, it is not clear that they belong to either group?

Y'all keep trying to recast what I'm saying into some claim that race is a black and white issue.

Your doctor doesn't understand your unique gravitational profile, that's all =:o)
