I can see why Germany got ruthless with the Jews if they were anything like these people...
none of these types of Jews lived in Germany
most of German Jews were "enlightened" and the ones that weren't were of a different sect of Judaism than the guys depicted above.
Hitler didn't have any justification. He just was filled with hatred, and it wasn't just directed at Jews.
You have a lot to learn about the differences between Western Europe and Eastern Europe.
