In fact, for centuries, Jews found sanctuary and co-existence in Muslim-ruled lands while facing persecution in Europe.
You have to keep in mind that the Ashkenazi make up 95% of the Jews of the world and they never lived in any Arab or any Muslim country ever and therefore they were completely unknown to the people of any Arab or any Muslim country ever – that is until 1882 when a bunch of white European Jews arrived as invaders and occupiers in Palestine. You cannot provide the name of a Muslim country where the Ashkenazi ever coexisted with the indigenous population, can you? It is true that when Spain expelled the Jews in 1492 and Portugal in 1496, they moved to the North African countries and also to Turkey where they had lived for 500 years.
