Speech patterns and accents are really fascinating. In Mississippi, you can, by listening, tell if a person is from the NE hills, the coast, The Delta or central state. I’m sure it’s that way in many states.
Also, the South isn’t all one place, even if we did try to seceed together. The "north South" (Virginia, NC,) is very different from the west South (Texas, western Arkansas). Mississippi and Alabama are probably the southest South, even though cosmopolitan parts af Florida are farther south geographically.
Point is, all of us have more in common than we do separating us. That goes for the whole country. The more we look ar our likenesses rather than our differences, the stronger our nation will be.
