Nice piece here. Can be rather summed up by PJ O\’Rourke\’s comment on sex.
There are times when the difference between men and women is crucial: like when trying to make babies. There are also times when the differences are not important: like when trying to trade bonds.
So with race: when looking for things like Tay Sachs, cystic fibrosis, beta blockers, sickle cell anaemia, genetic background is important. When discussing civil liberties it\’s irrelevant.
