One of my coworkers, a black gentleman from Mississippi (don't call him African-American, he'll jump all over you and tell you that his skin might be black but he's 100% American), has a huge Confederate flag in the back window of his pickup. His great-great-grandfather and all of his great-great-uncles served in the Confederate Army, with a number being captured at Vicksburg and one great-great-uncle dying during the Battle of Nashville.
David is extremely proud of his heritage and has stated several times that his ancestors were fighting for Mississippi and to protect their families back home.
