Interesting site, Jackie. I took a few linguistics courses way back when, and this site covers much the same ground that I recall from the old days. I still have some reservations about assertions such as:
From a linguistic point of view, there is no basis for saying that one dialect is more correct than another, just as there is no basis for saying that one language is more correct than another. All dialects are equally systematic, but they just have somewhat different systems.
I suppose the opening phrase is meant to soften what follows. I'm something of a stick-in-the-mud about all this acceptance of what I see as substandard usage. It may be that prescriptive is out and descriptive is in, but--as I used to tell my students--make sure you learn the "correct" forms just in case you ever decide to apply for a job.
