Colonial education or education, you are starting to sound more as if you are scared of education and research more than anything.
Studies have found that as I posted earlier, Ebonics uses subjunctives normally, whereas common english subjunctives are being phased out entirely. As you saw in this article, ebonics uses negatives in the manner of other languages, they don't cancel each other out as they do in standard english, Its common in ebonics for the word " be form" to be left out, as it is in russian languges, it also has a base of words that are used that aren't used in standard english.
Its pretty interesting when you read more about it.
