I don't. As a member of a small ethnic group myself, I really don't understand why. Whatever it was that we had to give to the world has been given. None of us have been treated cruelly for being of a certain race (for the most part). We just chose to move away, marry others (because we're not race purists, like many 'indigineous' activists, I suppose?), raise our children, and be happy.

Not every society has produced things of equal value, and it's not particularly offensive to notice that.
