I did specify "other factors being equal." A brain disease is clearly a special case, since the real advantages bestowed by first-hand experience (eg: better empathy, fuller understanding of symptoms) are negated by the doctor also becoming a mental vegetable. Further, unless you equate being "black" with having brain damage, how would that example even apply to the original issue?

The remainder of your comment rails against a position I do not hold, and did not claim to hold. My best guess is that you were thinking of Affirmative Action? Affirmative Action, as I answered someone else in this thread, is its own issue.
