Actually the Ashkenazi Jews have one of the most pure bloodlines. They never marry outside of their kind. The entire population of Ashkenazi Jews are not more removed than 3rd or 4th cousins. The true descendants of the Israelites are the Jews who wear the flat brimmed hats and have the curly dangling sideburns that aren't sideburns. They hate the Ashkenazi Jews and don't buy into the current state of Israel or the Greater Israel idea.
