My grandmother was a 'mischling' (mongrel), half Jewish on her father's side (a doctor who converted to christianity for convenience), and a gentile mother. Both died before the war, and she was orphaned, interrogated by the Gestapo, imprisoned (for listening to the BBC), and survived through begging for her life.

Though half her family were wiped out in the Holocaust, she still casually said to me in her old age that 'the Jews must have done something' to provoke such a response.

I don't hold with that, but it does give some indication of how brutal the world view was, and how everyone bought into the anti-semitism - even Semites. If you think she was a one-off, then read up on Wittgenstein, who wrote about the 'dirty Jew' inside him.
