It's best to face facts. There are multiple races within the human species, but that doesn't make any particular one of them better or more entitled than the other.
I must agree. There are observable biological signs of race, not only in measurable morphology, but also at the DNA level. And I don't see anything wrong with that. I find it much more harmful to whitewash and deny in the name of political correctness.
Personally I find differences between people are fascinating, and don't see any reason why they should be a barrier.
