Oh, I don't know about such stereotypes.
I'm fairly literate and I certainly come from southern stock on both sides.
I do find it sort of arrogant/judgemental of folks who don't even reside in the south to make
such blanket accusations of supposedly widespread ignorance down in these parts, however.
I hear it from both ends on this, actually.
"Natives" ask me all the time if I'm "from around here" (I actually am; both sides of the family
are from TN and I was born here) because I speak the way I do.
Conversely, when I speak to people on the phone from other parts of the country (happens often,
part of my gig) some will invariably bring up the same sort of thing - apparently I don't sound like
their preconceived notion of what a southerner is
supposed to sound like (I have almost no accent,
thanks to my family moving to the DC area when I was 14).
Know what it all boils down to?
Nothing is as set in stone (
especially stereotypes) as our media sells it to be.
There is very little absolute black or white in this world, especially when referring to people.
We're
all from somewhere else, according to how far back you go in the ancestry.
Sorry to make it less certain for you all.
Bottom line is, there is no such thing as a "typical southerner".
Oh, and P.S.:
Regarding KD's obsession with spelling errors? This website's own spellcheck is wrong - and often.

Of course, I wouldn't know that if I wasn't sort of like KD anyways, eh?
I get a little more snippy when I see someone who gets paid to write butcher the language, honestly.
