Five centuries of colonialism have produced in Europe and the USA the worst imaginable PTSS in history on the basis of a European and American managed genocide, culturicide, and humanicide in Black Africa, and the rest of the world with, what's more, black slavery. There is no excuse, no explanation. The PTSS takes unimaginable forms. For example, members of the educated middleclass in Europe try to adopt Black children they uproot from their homes, producing frustrated and often psychotic children and then adults. The middle-class moderately educated people who do this want to compensate for the crime of colonialism. An,d they commit another crime which is familicide generating psychosis or depression in the victims of such adoptions.
