Why do Jews still live in Russia? Anti-Communists blame the Jews for the rise of Bolshevism, Communists blame the Jew for the fall of Communism.
Not all Jews are religious Jews. In old Europe an entire city converted to Judaism overnight. The mayor - so the story goes - declared the city Jewish for political reasons. The descendants of those Jews - largely - are alive today. Sen. Chuck Schumer. Mark Zuckerberg. Ruth Bader Ginsberg. Well... These are the communists. On the other hand, Sol the bakery owner is a religious Jew likely NOT a descendant of Khazarian Jews.
Does that answer your question about why Jews continue to live in Russia?
At one time, applying to leave the Soviet Union would cost them everything. Sort of like working for or openly supporting Trump today.
Those days are over for now I recon. It used to be that you actually feel the oppressions in the air there. It was like a dark cloud. A heavy presence. Looking at current videos by Russians on Youtube, things are completely different, bright and fresh. Like it used to be here.
