But if you happily concede that it is inferior to English and part of an inferior culture, then how can you disagree with that premise? What is the artificial preservation of a dialect with no inherent value, no great works, and no attached positive culture but an enforced anti-intellectualism?

But I'm not supporting 'preservation' of this dialect, let alone artificial preservation. If Ebonics dies out, good. I'm just saying that no dialect is inherently less 'valid' than any other.

My problem is that people sometimes portray the manner in which some people speak as 'stupid', even though these people just speak the way people from a given region have always spoken (with changes, of course). Just because it's not the language that is taught in schools, because it's not the language of the political center, does not make those people 'stupid'.

No dialect is inherently objectively better than any other, or more or less valid.

If you do think that it is, you'd have to say that French people are dumber than Italians, because their dialect unquestionably diverges more from the 'proper' language (Latin) than Italian. Clearly, Frenchies were too stupid to speak that language properly.
