Perhaps Russian Far-Right are a big-tent that range from Pan-Slavic Nationalists, Eurasianist National Bolsheviks, Monarchists to Fascists. So like you got people like Konstantin Rodzaevsky, Anastasy Vonsiatsky, Alexander Kazembek, Nikolai Ustryalov and etc.
Since the Union isn't under Stalin, perhaps politics in the Union can be much more free and open.
Maybe the Soviet Union can tolerate Fascists, perhaps you have National Bolsheviks or Communists who seek to tolerate Fascists. That and you have Soviet Intellectuals trying to experiment with Fascism despite Mussolini's hatred of Communists, I mean in Fascist Italy there was a case of high-ranking Fascist politicians who sought to reconcile with the USSR and experiment with Communist Ideology, the same can be said with Ex-Communists turned Fascist like Niccola Bombacci who saw Fascism as a road to Communism.
