You keep talking about "Blacks" vs. "real Americans" as though "real American" is defined as "belonging to White culture".
Blacks in the US are not a "less-American" minority. US culture is multipolar. Why would Blacks assimilate to White culture? Why not Whites assimilate to Black culture? To me this sounds like saying Europe is bad at integrating minorities because French people haven't become German or English yet.
A big difference is that Blacks have been in the US for hundreds of years, whereas they have only been in France in large numbers since after the war.
