Have a look at the Civics test presented to "new Americans" (generally after 5 years of residing in the US).

Q. #60.
Q: What group of people was taken to America and sold as slaves?
- Africans
- people from Africa
Who is responsible for that disrespectful state of affairs? Diasporic Africans? No!
Who has been complicit in that disrespectful state of affairs (that is, what others are sensitized to about ("learn about") the historical contribution of the African presence to American society)?
"Foundational Black Americans" without a doubt.
The other questions that invoke reference to the African presence in America are Qs 74, 75, 76, 84, 85 and 100. There is very little there that imputes agency to black people or that values post-enslavement or that characterizes contribution or achievement and conveys that to the immigrant from Burkina Faso or Pakistan or Vietnam or China or Ireland or wherever else. So, "foundational Black American" advocates can continue to shadow box.
... without mention being made of Kwame Ture, Shirley Chisholm, James Weldon Johnson and a world of others whose injection into the debate would injure their contentions.
Bottom line ---
That's what a class of documented migrants are exposed to (those who "got in line"). That leaves the undocumented to form conclusions based on everyday experience, popular culture and structural racism whether they work in a chicken plant, hog processing plant or are standing outside a social services building wondering what it is.
