I understand the sentiment, but you are simply wildly incorrect. It incorporates tons of words and syntax and usage that came from their own sources. This is not a question among any serious language scholars.
I understand the reasons for disliking it, avoiding it, and judging those who use it. But it’s a true dialect as much as Southern English, Boston, Australian, British, Cajun, Apallachian, etc.
OK, you win; what you are considering “dialects” are simply accents to me.
When someone can’t piece to consonants together (for example, “project” becomes “projec”), it is simply poor English.
