I'm not downvoting you. But your position is untenable, and comes from a misunderstanding about what a language is. It's not that it's not politically correct, it's that it's factually incorrect.

No one is arguing that there is or isn't a class and racial component to who speakers of AAVE are. They are primarily black and poor. But that point is irrelevant. Kids raised where people speak AAVE will grow up speaking AAVE. Simply declaring it 'not a language' gets you nothing. It's not 'just slang', it's a system of speaking with its own set of rules, just like any other language.

Simply declaring that it is a language gets you nothing too. If every minor variation creates a whole new language, then almost no two people with a vocabulary of a few thousand words actually speak 'the same language'.

Sure, and if you want to go down the road of constructing metrics for language, you can. I should warn you that you will likely find it fruitless and arbitrary.

Your point about how every variation makes a language is correct. The term is idiolect. Language (like 'English'), is an abstraction over idiolects. But getting people who want to argue about "correct English" to an understanding of idiolects is more work than I can put into a comment during a work day. I'll try and dig up a general description of the issue and link it here.

Edit: http://en.wikipedia.org/wiki/Idiolect#Idiolect_and_language is the best I could do on short notice.
