I'm not opposed to everyone knowing standard English (which is a rather recent concept, btw). I just don't want to destroy the legitimate heritage of the various dialects and accents that people have had for hundreds of years. Does this bother you?
I'd avoid folklore anthologies if I were you.
Of course it doesn't bother me, or anyone else here. You're obviously reading more than necessary into what we're saying. As long as public schools teach standard English, and as long as we create a culture that recognizes the true importance of it, I don't mind if people have a second language (whether that is in fact a dialect or a true second language or something in between); nor do I mind that students read literature written in dialect. What I object to, as did Bill Cosby, is the apathy many parents have over insuring their kids can function in the professional mainstream.
