Since when do people join in to sing any state song at public gatherings?
“Darkies” is an old term but in no way negative.
And no, at the time, I don't believe he meant "darkies" to be denigrating. But times have changed. I have many black neighbors and friends, and I would never refer to them as "darkies."
What's the point of having a state song if it isn't played or sung somewhere -- at a state event or something? I'd be very interested to see the reaction of the players if someone were to play and sing Old Folks at Home at a Florida university sporting event. I imagine it wouldn't be pretty.
