Racism is easy to find in Georgia, as it is in every state. Boston is a very racist segregated place also, and it's not in Georgia. So is Chicago. I don't know of a major city that is not segregated significantly.
Georgia very nearly elected a black female governor. What does that mean? South Carolina has a black Senator.
Saying there are racists in Georgia is like calling water wet. Claiming nearly everyone in Georgia is a racist is an over generalization. And claiming it is uniquely true about Georgia and not other states is obviously false as well.
I also wonder how many of the black Georgians one could consider as being racists. Or the Hispanics. Or the well educated. And of course 60% of the population of the state lives in metro Atlanta, which doesn't mean there aren't racists here, but they do tend to be better educated than those in small towns about the state, and more progressive, and more tolerant, in general.
