Southern accents, Eastern accents, Northern accents and Ebonics

[SWTXBelle]

Well, linguistics studies what IS - not necessarily what you think should be. There is indeed a dialect known by various titles, but you can think of it as Network Standard English. Probably what you mean by "proper English" - actually spoken by relatively few outside of those who have had voice and diction or speech classes.
I think it fair to say that there is indeed a dialect, call it Eubonics or BSEV, that is identifiable and can be discussed in scientific, linguistic language. Transitive be, anyone?
