Racism is not based on reality. It rather creates its reality of “real” differences. It is not the actual presence of people from different origins immigrating to Europe that triggers racism. Racism existed also without immigrants. Racism just takes on ever new forms of existence. There is always someone who is invented as other, stranger, and fundamentally different, and therefore needs to be excluded. Jewish history gives numerous examples, how people can be constructed to be the other even though they have been our close neighbour for centuries. And we should not believe that the society of the 19th Century was more unified, because there was no one with a different skin colour living in Europe. There was always someone black enough: Workers for example. Working in the polluting surroundings of plants or carbon mines their skin colours were probably often not white indeed.
