You are going to have to tell me how the Ashkenazi are acquainted with the Arabs before 1882 when a bunch of starving and very poor Ashkenazi people began to arrive in Palestine from the ghettos of Eastern Europe? There was never a time that the Ashkenazi can claim that they ever lived anywhere in the Middle East before 1882 and prove it. The Arabs did not know these people because they never met! You should realize that for most people claiming an ancestry that is not theirs is extremely humiliating. Do you not feel humiliated every time you claim to be a Hebrew?
