After the Khazars converted to Judaism in the 9th century and then they moved towards eastern and western Europe, it did not take long for the European Christians to start hating them extremely and they desperately wanted to have them removed from their countries. What were the reasons? The main reason was because the Ashkenazi had always betrayed the countries where they lived. So we cannot expect them to behave differently towards the Muslims than they did towards the Christians of Europe.
