I don't think we are arguing that point.

Only whether "country music" reflects longing for the Confederacy, which of course would include slavery.

I would say that Dad Perkins' citation of Coe's song does fit.    Coe is known to be a racist (only really good song he ever did in my opinion is "You Never Called Me By My Name", which of course Steve Goodman wrote.)

For the rest of the song candidates, I think we are stretching to make the facts fit the theory.    Not exactly good scientific method.
