My mother’s not-Jewish German professor was arrested by the Nazis for being a pacifist. First they asked me if he’s Jewish. He said, “no”.
Then they asked him if he’s a pacifist. He asked, “How do you define pacifism?” They said, “That proves you’re Jewish. Only a Jew answers a question with a question.
He escaped Germany right away.
True story. I did not make this up.
