By “nonwhite” you mean “black.” Be clear about who you’re talking about.

But if that’s the principle—why does that justify discrimination against Asians immigrants whose ancestors had no property in America, but far less valuable property in third world countries?

If we are going back to people’s grandparents, a house in even a redlined neighborhood in America is much more valuable than a large house in my dad’s village in Bangladesh. Even a segregated American school is better than the village school he attended which had no walls.
