I know Russians are responsible for everything wrong in the world ever, but when I say that there is a rich tradition of antisemitism in Europe, I mean since at least the time of Shakespeare. Merchant of Venice kind of thing.
In Germany, Nazis didn't just invent antisemitism out of thin air. They exploited a common sentiment held by the working class. If you think that's due to Russian propaganda, well, we are also under your bed. Be very afraid.
Lastly, there is a trend lately to label "problematic" any sentiment of insufficient piety towards all things Semitic. This is a great culture, but it has shown that like any other great culture it is capable of genocide.
