Thank you for writing. I appreciate your comments. Re “ebonics”, ask your friend to explain how and why, if “ebonic” speech is derived from Africa, it doesn’t exist in the populations of African descent in Jamaica, Barbados, Trinidad, et al - and where is it in the former English colonies on Africa?
I had that argument back in the early 1990s. I tried to point out it was a combination of bad grammar and slang, while she contended it actually had “rules” and thus was a language. I’m sure she read some college professor’s writing trying to claim that was so. She was a liberal lesbian I only had passing contact with thankfully. My contention was still- good luck getting a decent job talking like that.
