RadicalModerate,
Another thing you might also want to point out, is that while its true that the South was controlled by the Democrats for a long time, and the South was strongly democrat during the Civil War, to try use this fact to argue that the democratic party today is a racist party is ridiculous. Both political parties have changed radically between now and the Civil War. In fact both the Democratic and Republican parties are really different than they were in 1950s or the 1960’s so to attack either party today on what most people in them supported over a century ago, or even fifty years ago, is pretty much fallacious.
