I asked a young black woman about growing up during Apartheid. She replied that there hadn't been too much of it where she grew up because she grew up in Port Elisabeth during the 1980'ies, where the Apartheid regime slowly but surely was coming to its end and where they actually in certain places already, experimentally, were mixing the different races, but did add that her mother had not only told her about bees and flowers and men and women, but had told her about bees and flowers, men and women and white people. Most racial groups have extremely stereotypical prejudices about the other racial groups.
