It shouldn't. It's very important to understand that Hitler's government and governing philosophy was socialism. Hitler was no more "right wing" than Karl Marx, Josef Stalin, or Hillary Clinton. They're all socialists. So-called "liberals", whether they be Jew or Gentile, are actually socialists, and are in the same camp as the perpetrators of ALL of the 20th Century's great genocides.
I wonder what Harpo Marx believed? :-)
