What country in the world today engages in the most extreme anti-Semitic persecution? The Soviet Union. It's not an accident, because if you have a society with concentrated power, if you have a collectivist society, it's going to be in a position to exercise the preferences and prejudices of its rulers. Moreover, it's going to have an incentive to do so, because it's going to need a scapegoat and it will choose some group like the Jews or the blacks to be the scapegoat.
