It’s a question of Judeo-Christian values. Who cares what damned color you are?
The question of who is or is not "white" has changed with practically every generation. There were times in the 1800s when the Irish were not considered "white"; at the turn of the century the Italians were not considered "white," and Russian/Ukrainian Jews were certainly not considered "white" until well after WWII.
It is telling, I think, that more long-term-American Hispanics are beginning to think of themselves as "white": it doesn't mean they have dumped their heritage or are trying to "pass," but that they have accepted long-term-American values, and see themselves more as Americans than as an ethnicity, just as previous generations of immigrants have done.
The same thing could happen in one generation with American blacks, with only two actions: first, the re-establishment of the nuclear family, both within the black community and in inter-racial marriages, and second, the popular shaming of race-baiters--including people like Sterling, but also people like Sharpton, Cummings, and Holder.
