I can trace my genealogy to Spain from both sides of the family. on my mother’s side the priestly cast that was not allowed to intermarry even a convert. On my father’s side from Spain to Germany and Poland. We know Spain had a large Jewish population and we know that in the year 1000 the king of Poland invited Jews to come to Poland.
You seem to know squat about both Jews and Arabs. Egyptians are not Arabs and neither are the Syrians, Lebanese Iraqis, Kurds or Bosnians. The vast majority of Muslims that comprise what is known as Balestinians.
