Someone with a Stalin pfp posting this is brutally ironic, since the Bund was forcibly disbanded in 1921 by the Bolsheviks and a great deal of former Bundists met with grim fates at the hands of the Soviets:
David Petrovsky, Mikhail Liber, Fanny Nyurina, Isaak Nusinov, Yakov Bykin, Yakov Drobnis, Joseph Meerzon, Isaak Illich Rubin, Moisey Rukhimovich, Mikhail Mednikov, Moshe Gutman, Mark Donskoy, Abram Merezhin, Aleksandr Zolotarev, and Israel Leplevsky were all shot during the Purges.
Victor Alter and Henryk Ehrlich were both shot on Stalin's orders.
Aron Sokolovsky, Mikhail Borodin, Isaak Goldstein, Anna Rozental, Aron Vainshtein, Moisei Natanovich Gurvich, and Moisei Rafes died in the GULAG or Sovet prison.
Samuil Agurskii died in Soviet exile.
Zakhar Grinberg died in Soviet prison after being beaten to death.
To be fair, though, Polish Bundists often did not fare much better.
Simon Dubnow, Mordechai Gebirtig, Michał Klepfisz, Pati Kremer, Maurycy Orzech, Aron Skrobek, and Abraham Blum were all murdered by the Nazis and Szmul Zygielbojm committed suicide to protest the apathy of the Western Allies and Polish government in exile with regard to the Holocaust.
