The author is drawing a parallel between the laws of racial segregations. In 1935 Germany, not too many people could have preidcted the Holocaust despite the segreation laws. I guess the real concern for a Jewsih person is to be supportive of laws earily similars to the ones enacted in Nazi Germany . Remember that the aim of the German law was to force the Jews out of Germany. Can you tell me that the purpose of the Knesset laws is anything but a tool to force non Jews out of Israel??
