You don’t know many Jewish people and the others have chosen not to interact with you.
My guess is that you said and did nothing for your Jewish neighbours and classmates and colleagues and friends on October 8th. I’m guessing you also said nothing when crowds gathered outside Sydney Opera House to chant “gas the Jews”.
Jews have an intuitive sense of who would help them if the Holocaust happened again. People who didn’t speak out in those days? They went on the “don’t rely on them to hide us in their basement” list.
