Of course there is a proper english. As defined by standard grammatical rules of the English language. A dialect is a variation upon that. I am not saying “black people don’t speak proper English”. There are plenty of black people who speak proper English, the same as there are plenty of white people who speak proper English and plenty of white people who speak dialects. I am saying that any and all dialects are not formal English, by definition of what the grammatical rules of the language are
Really good reply, thanks for the effort you put in. Its good to see they did compare with other dialects. It’s interesting that the same bias was not seen.
I would still disagree with the statement that AAE could be considered equally proper to textbook, grammatically correct according to the Oxford English dictionary (or the American equivalent). A dialect by definition is an adaptation of the language from the standard ‘proper’ grammatical rules.
