John McWhorter Dialect Quotations

Black English is something which - it's a natural system in itself. And even though it is a dialect of English, it can be very difficult for people who don't speak it, or who haven't been raised in it, to understand when it's running by quickly, spoken in particular by young men colloquially to each other. So that really is an issue.

It would be good if teachers could genuinely understand that black English is not mistakes, it's just different English, and that what you want to do is add an additional dialect to black students' repertoire rather than teaching them out of what's thought of as a bad habit, like sloppy posture or chewing with your mouth open.
