This seems a way to say “These Blacks are the oppressed Blacks, the others aren’t”
Not really, just acknowledging our differences. Just like how not all White people are the same. A Serbian has very little in common with a White American, for example.
The only thing I will push back on is some of the rhetoric that SOME (not most or all) Black/African Americans will expose about Black immigrants. Some will say that Black immigrants are "leeches", "tethers", "aren't really Black", "ungrateful", etc. That's wrong and ignorant.
Of course, SOME (not most or all) Black people from Africa & the Caribbean will say stupid & ignorant stuff about Black/African Americans too. That's also unacceptable.
My ancestors were indentured servants, about as close to slaves as whites ever got in this country. Yet it would be absurd for me to get special privileges or anything today by recording this, which is why data is generally reported as just “white” for all white people. Racism today is based on people’s knee-jerk perceptions of skin color, not DNA tests.
