Then, too, the South represented blood-- not red blood, but blue blood. The difference is in the length of the stream and your distance from its source. If your own father was a pirate, a, robber, a murderer, his hands are dyed in red blood, and you don't say very much about it. But if your great great great grandfather's grandfather stole and pillaged and slew, and you can prove it, your blood has become blue and you are at great pains to establish the relationship.
