Slavery isn't really the issue. It's race.
That's the problem with being so evasive about even describing race. There was so much baggage around the use of Caucasian, Negro, Mongol, etc., that no descriptive terms have ever been acceptable after them. The euphemisms of "Asian" or "People of Color" have been used with the limited meaning of "Oppressed" or in this case, "Not Preferred Sexually."
Then there is the whole issue of the categories of race used by previous centuries didn't even include all the large groups of phenotypes. (God. The damned spellchecker on JUB is so illiterate, it doesn't include phenotype. Shit.) And, the categories didn't work because Latin wasn't a race, yet it needed to become one to speak to oppression. So, we wound up with "People of Color."
That followed an evolving agenda in which it was just white people who were the big problem, because a) we're Amero-centric in that discussion, b) it's awkward to acknowledge that Italians, Jews, Irish, and other immigrant ethnic groups were first discriminated against and oppressed, and then quickly became the racists and oppressors as they succeeded in the new land. But, none of them were non-whites.
It's actually kind of a mark of progress that racist accusations have had to reach out as far as "you don't date me" in listing forms of oppression. Poverty is and was the largest social divider in the US. Poor people of color and light color share popular music, attend the same churches, live in the same areas, and schools. They are mixed, but predominately minority in increasing numbers.
Middle class people of color and light color share popular music and attend the same churches and live in the same neighborhoods, and schools. They are mixed, but predominantly majority, but it is in decrease.
Upper class people live in the mountains, on the coasts, and in the hearts of cities in estates that are like walled parks or in high rise isolation. They do whatever they please, date whomever they please, and rule the rest of us.
The lingering obsession with slavery ignores that every ruling class restricts the rights of the working class. It was true and is true the world over. Even in socialist countries, the workers still don't rule.
But let's continue worrying about who's dating whom. That's revolution for sure.
