Which is why it's important for centrists, especially in the GOP, to move carefully. This is a chance to separate the sheep from the goats. There must be vast numbers of southern white conservatives who are every bit as small government, religious freedom, and even states' rights as they were yesterday but who also can put themselves in their black fellow citizens' shoes and think, "Yeah -- seeing something they hold akin to the Nazi flag when they go to the statehouse has got to sting. We're big enough to see that." And then there are large, though hopefully not nearly so vast, numbers of southern white conservatives who are going to go apesh-t over this, blame Obama, and buy a few more guns to prepare for the coming of the UN copters.
From what I've seen there are just as many local GOP as Democratic figures calling for the removal of confederate symbols from state flags, grounds, and license plates. This could be a moment of unity and healing for all Americans, and we haven't had many of those since the immediate aftermath of 9/11. This is something that large majorities of people seem to be agreeing on, regardless of their political identification.
So everybody be cool and don't blow it. Any time we can move the hands of the Second Civil War clock back a few minutes, we should do it.
