That kind of thinking is so 1960 though. I've lived in intergrated neighborhoods in the South for 15 years and I have yet to hear anyone complain about a black neighbor.
After 15 years, I can't imagine you would. How would you feel if the black boys started hittin' on and datin' the white girls...possibly your daughter?
Isn't it, though? I live in an integrated neighborhood, have for 20 odd years, and it's no big deal. I didn't see anyone putting up "for sale" signs, either, except for those who were moving for job reasons, a bigger house, a smaller house (or into a condo), stuff like that.
