No, it's not called Bolshevism. The Bolsheviks were shooting immigrants (as it happened with thousands of Polish communist exiles) and were extremely violent in their suppression of ethnic minorities.

Speaking of the latter, it's a fun fact how the Soviet Union had a western-inspired entire genre of easterns ("osterns"), typically about the brave Bolsheviks (Cheka or Red Army members) fighting the evil Muslim "bandits" in the Central Asia during or after the Civil War.
