Explanation: Dixie is a pre-Civil War Southern tune. During the US Civil War, it became popular as an unofficial anthem of the pro-slavery Confederacy, while the anti-Confederacy North dropped a fire variant for liberating the South from anti-democratic slaver shitheads.

If you hum Dixie, and it is a good tune, be careful that no one mistakes you for the wrong kind of Dixie enjoyer!

As Abraham Lincoln himself said, slightly tongue-in-cheek, at the conclusion of the war...

I have always thought `Dixie’ one of the best tunes I have ever heard. Our adversaries over the way attempted to appropriate it, but I insisted yesterday that we fairly captured it. I presented the question to the Attorney General, and he gave it as his legal opinion that it is our lawful prize.
