Well, I would like to oppose two things to this: - this may be exceedingly US centered, as in my country it is not quite as obvious. In fact, the word "race" does not even exist in my language (at least in the American meaning, the equivalent is only used for animals). - I think questioning assumptions allows one to better discern what is inherited prejudice and what is a universal fact. As you may guess, I think this is an instance of the former and certainly not a permanent/immutable state of things. Furthermore, I think when one claims something is "substantiated", one should come with strong evidence.
