@Linkat,
I can recall one episode that occurred on the SouthSide of Chicago, at a time, when integration of that part of the City was in it's infancy. A State Street bus pulled up to pick up a white woman standing at the bus stop.
As the bus stopped, a black man on the bus, opened the window, shot a ball of spit into the face of the woman, and laughed. The woman did not board the bus and did not attack the black man.
The white woman cleaned the spit off her face, walked home to her house, contacted a very eager black broker , and within days, sold her home for far more than it was worth.
She then moved out to the suburbs, bought a house in an upper-middle class neighborhood and lived a very pleasant life with her neighbors, who didn't go around spiting on others .
The area of Chicago, where the spitting incident took place, once all White, is now all black. It is a giant, rat-filled slum, infested with individuals who are poverty-stricken and hopeless. It is basically, another ghetto and totally without any hope of "integration" by other races.
