the same way you have rappers who grew up in the suburbs claim big cities even though they live in the outskirts.
white country singers been claiming small towns with historic confederate history even though they from bigger towns/cities (pop wise) with no real confederate history in that state...
hell some not even from south
as for this line
Aldean opens the song: 'Cuss out a cop, spit in his face. Stomp on the flag and light it up. Yeah, ya think you're tough? Try that in a small town.'
small rural towns that was on the side of the "GREYS" have no respect for the "Yankee" flag
so to see yellowhammers/greys all of a sudden claim they respect/love the flag is funny. Kap had to made more confederate sympathizers buy Ol' Glory than any war in this country history.
