My grandparents did, and I have direct testimony to their struggles and persecutions. I can also speak of many other persecutions, sometimes endured at the hands of reshaim.
This is a period for edifying one another and embodying ahavat yisrael. We have enough enemies from among the goyim. This is why I believe one Jew hurting another Jew is one of the saddest things that goes on. We need to stand together and accomplish our collective tafkid as a nation and as an am segulah. Sephardic, Ashkenazic, Reform, Conservative, Litvish, Chasidishe, etc. ought to make no difference. Regardless of whether Jews lived under Muslims or Christians, there was persecution, and I am called to make my family’s story known. I know where exactly my ancestors came from in Syria and Yemen (too bad I can’t know where my Syrian ancestors originally lived in Spain and Portugal), and to make the horrors they endured known to the world is one of my goals in life. I’d also like to learn more about my mother’s family’s Bnei Anusim roots (as many as 30% of Southern Italians have Jewish ancestry, and many of them are returning to the Jewish People) and make the story of the Jews of San Nicandro and other places in Italy known. We are living in remarkable times, where all of the dispersed seed of Israel, no matter how distant they may be, are being drawn back into klal yisrael.
