Racists find themselves increasingly isolated by the more reasonable members of society
For racists the group is defined in very simple, easy to recognise terms. If you’re the same colour as ‘us’ then you’re one of ‘us’. If you’re a different colour then you’re ‘them’. Since the problems we face can’t be acknowledged as part of ‘us’ it must come from ‘them’.
It’s no coincidence that racist, xenophobic groups like UKIP and the BNP began to experience electoral success just as the economy crashed (mainly due to the actions of white bankers). Such discrimination is predictable at times of social pressure.
It mirrors the rise in anti-semitism in medieval Europe as the Black Death spread across the continent and the people scapegoated minorities. It mirrors the rise of the Nazis in Germany following the disastrous economic penalties enforced by the treaty of Versailles at the end of World War One. The German people needed someone to blame who was not ‘us’. They chose the highly visible minorities of Jews, Blacks, Communists and Gypsies.
Let’s examine the psychological processes in more detail.
