Regardless of the school board debating the potential validity of AAVE, I think it's misguided to experiment with asserting such "correctness" to teach kids that will grow up in a world that doesn't regard it as such. Save such philosophy for later academics, where the author/speaker can make a conscious choice of use - similar to the stylistic, but "incorrect", use of 'But' or 'And' to begin a sentence.
This is not philosophy at all. This is purely technical. The differences between AAVE and standard English (or should I say American?) are consistent . They are spoken by a lot of people. They follow precise rules (a grammar, actually). They're not erratic. So you can't call them "errors". The only other choice is to conclude that AAVE is a language —or a dialect. Telling that to kids can only have good effects. Firs…
Rastafarian use of 'Me' for 'I' makes sense and is consistent.
Using 'bad' to mean 'good' probably isn't a good idea if you are an aircraft mechanic.
