There are so many facets of this and why too many don't do anything. One is that being a second class citizen is acceptable if you can live a decent life then white supremacy is literally an acceptable 'evil' in order to live better.
And when their wake up call comes and they can't shuck and jive out of it, then temerity is that they expect, no DEMAND we march, protest, etc.
Another facet is they are the buffer class in America. White people treat foreign blacks who are noticeably foreign (accent, mode of dress) 'better'. They know that black person doesn't have that history of conflict with them. If you are FBA or speak and act like an FBA then you are treated as such. Even if they know you have foreign history, they look for mannerisms that say what side of the fence you sit on.
I can't recall where I read it but it said that what ever gains foreign blacks in America, by the 3rd generation they are at the same level as FBAs.
Native Africans started coming to America in numbers more than a trickle since the mid to late 80s and into the 90s. It will be interesting to see if the Nigerians can maintain what they think they have by the 3rd generation. That generation will be culturally American linguistically, etc, and will have been born and raised in America facing the same BS. There will likely be a disconnect between them and their grandparents. They will see black American women as their dating option. Not all, but I think most will.
