People who face racial discrimination, who are exposed to the experience of being told they are worthless because of whatever accident of birth they happen to fit into that is put down by others to deal with their own inferiority problems will, on occasions, adopt the Stockholm Syndrome condition in order to curry some sort of special favor. I think among Blacks it's called the Uncle Thomas effect, West and Thomas. There are also Jews like Stephen Miller. I see these types as among the sickest of the sick. But they are a product, of racism. I don't think they were born that way. People will do anything to recover from being made to feel worthless, in my opinion. I see the condemnation of the other as the inevitable result of being made to feel being worthless for belonging to this or that identifiable group.They forcibly sterilized most of their limited black population. So I guess you could say it's a good thing for him his grandparents didn't live there, or he wouldn't exist.
But we create what we fear because being a racist is an identifiable group and if the shoe fits you are considered worthless by people who having been exposed to bigots learn to hate them for the contempt that manifest. They aim to make everyone around them feel as worthless as they do.
