Nah, if this was the UK where Blacks are 3% and declining minus immigration I might agree but Black folks are way to big as a population and at the end of the day, the USA is more accepting of IR than the past, but we aren't some Brazil or France. We even have the highest proportion of mixed folks marrying Black in the Western world. We have issues but it is not too late.
A huge proportion of this happens in places like NY and CA but in the South will whole Black communities or regions, especially middle class like ATL or Charlotte, it won't go all the way. We are stuck together whether divesters and SYSBM like it or not.
