Anti-semitism was rife throughout the world, neither the Russians or the Germans were unusual in this regard.
Francine Christophe wrote about central european Jews as having suffered centuries of discrimination ("so were just Jews") they spoke Yiddish (she didn't) so they didn't view her as Jewish, a diferention she points that the even Hitler himself failed to make.
History teaches us that a people without a country are ripe for victimisation, if you go back to the 19th century you'll see the abuse of the Greeks, the Armenians and the Assyrians, the state of empires tends also to conspire to abuse it's subjects as the executive and the legislature is also the oppressor and as a consequence validates and excuses itself.
Such abuses transcend religious boundaries and tend more to revolve around the more subtle racial overtones, the Roma gypsies are a case in point (even today) and the third Balkan war (technically still being waged) is another.
