Well, that would depend on your premise, Dave. If your premise is that it has been definitivly established that the people who became the Ashkenazi Jews lived in the area of what was once called "Palestine" prior to the people who became known as "Palestinians", then your "facts" are most certainly in dispute. If you read the contents of the last link I provided, about the genetic research being done on both groups of people, you will see some very good challenges to your "facts".

If you are not trying to assert that the Ashkenazim preceeded the "Palestinians" in that area, then we are not in substantial disagreement.
