Pretty simple equation...you take the only region of the country that isn't kissing liberal ass and you divide them. You take away their culture...regional pride...identity. You use something like a regional tragedy and you turn it into a referendum on race relations(which is better here than most places I assure you). You further vilify, shame and berate a good people for events that were not of their doing and they finally submit and become the mindless robots the rest of the country has become. Pretty good strategy...better than anything Sherman could come up with...and you destroy from within...now lets see if the South bites on it.
