You say you never observed racist attitudes till you moved North.
I differ slightly with you-I observed MANY racist attitudes in my three years in the South,but none of which I hadn't previously observed in the North!
I lived for the first 32 yrs of my life, up North, in Chicago...then we moved to North Carolina, and lived there for 5yrs...
I saw racist attitudes, in both the South and the North...I agree with you, it was slightly differing, one area from the other, but the attitude was there....
