You are precisely pointing out the idea of the article. African American Vernacular English (often referred to as Ebonics) is just another dialect of English that is studied by linguists just as any other. Much of it is influenced by slang and pop culture.

The conclusion one might draw from your comment and the research is that to most Standard American English speakers, AAVE sounds unprofessional.

I suppose I don't see how there is any distortion going on.
