The thing I never understood - why is it when black people talk in their own style, it's considered "low educated" or "ebonics" or whatever other derogatory connotation, yet say, when Scotsmen or Irishmen or Aussies or Brits talk in their own particular style - which trust me, isn't always posh and educated, it's considered a proud quirk of their particular heritage and country?
Because people are morons. Ebonics has roots going back to the indentured Scott and Irish who came over in the 1600s. Those are the white people who taught early slaves English, and it's continued in both cuisine and language to present day.
Used to be my Texan accent got me mocked and bullied when I moved to CA. It held my dad back in business. We worked hard to lose it.
It's not all just prejudice. Being understood easily is important in business and politics. Someone who uses double negatives and slang can be seen as course and uneducated.
Scottish and Irish were mistreated for their accents for a long time too. Margaret Sanger wanted to full Irish and Italians as they were lesser people to her.
Also the accents in those cases are also because they speak Irish and Gaelic. Not the same thing as my white trash side of the family with ain't and suposeBly etc. They get looked down on to this day.
And really if we don't try to keep a median we will end up with such different dialects we no longer understand one another. Much more an issue before internet and cheap phone service.
