There are also still in existence organizations like the "United Daughters of the Confederacy" and "Sons of Confederate Veterans" both founded in the 1890s.  You can hardly go into any small town and city and not see a statue of a confederate soldier prominently displayed.  Are you a fan of the UNC Tarheels?
