For over 10 years, I belonged to Sisterhood Salaam Shalom, a nationwide organization of Jewish and Muslim women, originally founded to develop understanding and empathy between the two groups. At the first meeting of my chapter in 2015, I asked the Muslim women to estimate the number of Jews in the world. They agreed on the number 500,000,000. To this day they will not accept that the number of Jews worldwide is less than 16 million notwithstanding that they are educated, upper middle class women, most with advanced degrees. I recently asked my physical trainer, a bright young Christian man from Florida how many Jews exist in the world. His response was half a billion. He, too, was incredulous when I told him the actual number.
