There is so much wrong in this statement, but more history required to explain it than a single post can cover. I'll try to cover only a few right now:
- The more famous antisemitic movement in Germany, while still fully responsible for its actions, used earlier Russian-published conspiracy theories as its foundational documents.
- The antisemitism of the late Russian empire was to the point that millions left to escape it.
- In the late Stalin years, Jewish figures of note would end up either assassinated or imprisoned, with rumors abounding of a mass deportation coming.
- In the years beyond and up to the collapse, Jewish culture, language, and religion were almost completely suppressed. References to the Holocaust could not mention Jews as victims. Systematic and state antisemitism was tacitly allowed, even encouraged.
- By the time of the collapse, almost all Jewish cultural knowledge had ceased to exist, only the most basic and vague knowledge remained. (Contrary to popular belief, the Nazis only played a partial role here once they lost - much of this culture still existed in 1945).
To diminish the intense level of antisemitism by comparing it to anything in America is absurd, and highly problematic.
