Have you seen the SAT scores for black African immigrants who, BTW, are presently at the pinnacle of academic attainment in the USA and the UK? Most are bilingual at the least and are becoming doctors and lawyers
or hold advanced degrees in the STEM disciplines. You'd better pull your head out of the 50's and join us in the 21st century...you are way behind the times.
Yes, African-American immigrants outperform American African-Americans. But, they still fall far behind whites on the SAT, dumbshit. And, those immigrants who are displacing native blacks in filling black quotas are the cream of the African black crop (they perform slightly better than native blacks because they don't self-sabotage). Even with social promotion PhDs (i.e. bullshit PhDs) being handed to blacks, they still represent a very, very small fraction of STEM PhDs issued.
