Many moons ago there were a bunch of African-Americans who went back to Africa in search of their “roots”. They were dismayed and shocked that the locals did not welcome them home, but rather looked down on them as interfering Americans.
When they pulled the African-American card, the locals bluntly told them that they knew nothing about Africa or its history or to the country they’d come. They were Americans and they should butt out and go home because they were not wanted in this part of Africa.
IIRC, that happened to a few of the “legacy” black panthers. That experience shut a lot of them up.
The civil war in Liberia was fought between “native” Africans and Liberians descended from slaves returning from America. The former were suppressed, and educated only enough to serve the “American” Liberians; they picked up guns and ran them out (many are now here in the US as war refugees).
I remember that incident. The American Blacks were discriminated against for their mixed-race appearance and called “kanaka”, which I read meant “cotton-picker”.
It was following the 1977 miniseries “Roots” that many American blacks went to Africa in search of their own. The aftermath went underreported as native Africans treated them with contempt (”you are the descendants of slaves!”) or scorn (”all of you so-called blacks have mixed-race ancestry!”).
Alex Haley, the author of “Roots”, journeyed to the ancestral land of the fictitious Kunta Kinte, but had little to say about it afterwards.
