I've always been under the impression that the term "WASP" was only really relevant in the North, and particularly the North East, in dichotomy with the waves of Irish, Southern, and Eastern Europeans who flocked to the region in the late 19th Century and their decedents.
In the South, the term isn't really relevant, considering that it arguably applies to almost the entirety of the white population of Southern Stock.
I suppose that saying that southern whites are 'WASPs' is sort of like saying that southerners of Cherokee ancestry are 'mestizo'. It fits the technical definition, but it's not relevant to the society in question
A good hunk of southerners are Scottish or Scots-Irish.
