That seems like a very inflammatory statement. I doubt what most african americans want out of desegregation is their culture wiped out and replace with american white culture. The more apt solution would be to stop being prejudice towards other american subcultures.
It would take a lot of confidence and charisma even for me to pull off my local white, urban dialect in the workplace. I really don't think it's asking too much to adopt a standard depending on context and audience.
Agreed it's a cultural one. African Americans aren't a race they are an ethnic group with their own culture including dialect. This dialect isn't shared among african americans and lets say Nigerians.
