Doesn’t matter who uses it; anyone with a grade-school understanding of basic grammar knows such usage is incorrect.
Your questions don’t deserve an answer, except for one. Yes, I AM a Southerner and an American. I’ll live and die loving the South.
You say you’re not a Northerner/Yankee, just American, and yet you just posted that you’re glad you’re not us.
Which is it? Can’t have it both ways, LOL.
I’m glad I’m not a Confederate. My ancestors fought them. And the Klan. I’m a Catholic and the Klan had no love for Catholics. Would you die an American? Why the bow to Balkanization?
