Sorry, Yehuda, there were many Jews in the high ranks/inner circle of the Bolsheviks - Trotsky was a Jew; Genrikh Yagoda, the head of the NKVD, was a Jew; Zinoviev was a Jew; Radek was a Jew; Kamenev was a Jew; Litvinoff was a Jew; and even the assassin of the Czar and his family, Yakov Yurovsky, was a Jew.
And over time, Stalin had them all eliminated. Maybe some Jews were attracted to the Bolsheviks, because of their hatred of the Czar....but the leadership of the movement despised Jews every bit as much, but found them "useful."
The widespread perception in the period 1918 thru the 1940's was that the communist movement had a disproportionate number of Jews, which lead to a higher degree of anti-Jewish feeling from those who had suffered from Communism, like the Ukrainians and the Poles.
“Yehuda, there were many Jews in the high ranks/inner circle of the Bolsheviks”
Kind of. It’s more like the Russian Nationalists and Russian Orthodox groups flat-out promised the expulsion and murder of Jewish Russians, and the commies told pretty lies, so the Jewish Russian went their by default.
