re: Ebonics grinds my gears.

African-American Vernacular English is a legitimate dialect of American English. I believe it is one of the few American dialects that remains non-rhotic, and has remained relatively distinct despite all other regional dialects, broadly, merging into an American standard. It has its own conjugation structure and grammar rules, and those rules have been remarkably resilient in the face of a de facto standardization project that began with the use of regional accents through media to give the appearance of standardization, specifically using rhotic, nasally dialects like Western New England and Mid-Atlantic. I think the odd conjugation and non-rhotic combination adds to the "uneducated impression," though for some reason AAVE has more critics than similar non-rhotic accents of New York and Boston.
