There have been tensions in the NYC area between these two groups for years, as a growing Hispanic population gradually takes council seats and such from blacks as their populations recede. Both groups were targeted with race-baiting by Dems, now Hispanics want payment. This was even an issue in selecting the DNC chair, and the Hispanic Perez beat out the black Ellison.
Dems can never keep everyone happy when they promise everything to everyone; I suspect this led to Trump winning white women in 2016.
I don’t know if you say that Amazon was looking for a new location. One of their key criteria was “diversity”. They calculated it by determining the percentage of the population that was foreign born.
Wonder what Maxine thinks about that discrimination against native born black people?
