Isn't it shocking that many African Americans STILL have the broken English accent of our ancestors?

I have a soft spot for "ebonics" as crazy as that sounds. I DON'T mean slang words or anything, but the broken English of it, like I've heard some people say "We at the store" or whatever (we at the sto, lol) you know how some people talk like that? Usually in neighborhoods with large Black populations too? I read a book called "Africanisms in American culture" that had a chapter about the way many African Americans speak, and the reason for it is because many African languages along the Western coast at the time of the slave trade lacked the same grammatical structure of English, so when Africans came to America as slaves and couldn't get a proper education and had to learn English on their own, they meshed the grammatical forms of African dialects with English words, and after so long many African Americans still speak that way because of segregation and most staying in areas around each other. Isn't that kind of cool though? Like its just cultural, but Americans are so ignorant to anything that they never question a thing so they see it as stupidity or something.
