@edgarblythe,
Your point is well taken. No one in the Soviet Union set out to extirpate religion, nor to force people to abandon their religious beliefs.
In about 1700, Petr Alexeevitch, the third Romanov Tsar (known to history as Peter the Great), made all of the clergy and monastics of the Russian Orthodox Church employees of the state, and undertook the support of the "physical plant" of the established church. His father, Alexei Mikhailovitch, had fought a monumental battle with the Patriarch Nikkon before overthrowing him and replacing him. Peter intended to have no enemies in his rear while he fought what proved to be a long and devastating war with the Swedes.
It has become a shibboleth of hysterical, ranting religionists that the Soviet Union was an atheistic state which killed millions of Christians. There can be no doubt that the Soviet Union killed millions--there is considerable reason to doubt that they killed them
because they were Christians. At most, a few thousands were killed who were clergy or monastics of the Russian Orthodox Church. However, they fell victim to their own decision to support Admiral Kolchak and the White Russians. Clergy and monastics who kept aloof from that struggle large did not suffer directly. They all suffered indirectly because the state withdrew its support for the established church.
Many examples are advanced, the most popular being the myth of the slaughter of the Kulaks (a myth to the extent of the scale of the deaths is alleged). After the collapse of the Empire, the two remaining political parties other than the Bolsheviks were the Peasant Party and the Socialist Revolutionaries. The Peasant Party wanted to distribute land to the peasants, and the Socialist Revolutionaries support their program in their attempt to wrest power from the Bolsheviks. Stalin was well aware that once peasants got land, they had no further interest in revolution, and that would have taken away the extraordinary power which the Bolshevik state was able to wield. So, Stalin undertook agricultural collectivization, and the deportation of the "Kulaks." Kulak means fist, and was used in the sense of tight-fisted; it was a propaganda ploy against those peasants who have gotten land from the Peasant Party and the Socialist Revolutionaries. When Fanni Kaplan (a.k.a. Dora Kaplan) attempted the assassination of Lenin, Felix Dzerzhinski and the Cheka (All-Russian Extraordinary Commission for Combating Counterrevolution and Sabotage--ancestor to the NKVD and the KGB) had all the excuse they needed to go after the Socialist Revolutionaries (of which Kaplan was a member) and their associates the Peasant Party.
Stalin moved as soon as he could to break up the land-owning peasants, especially in the Ukraine. Despite wild, hysterical claims by religionists, this was done for policy reasons, and had no reference to their religious beliefs, if they even had any. Also contrary to the hysterical charges, somewhat less than a million of them died in the deportations, not millions and millions of them (there weren't millions and millions of them in the first place). I don't suggest that it should be brushed aside because there weren't a million of them, it was a horrendous act of indirect murder. However, the figures are conflated with the millions who did die in the resulting famines. Before 1914, Russia was a net exporter of grain. After the deportation of the Kulaks, the grain production of Russia and the Ukraine never recovered.
Those millions who died in the deportations and the subsequent famines were not murdered outright because of their religious beliefs. Nor was that the case with those sent to the gulags. Perhaps some who attracted the unhealthy attention of the state did so because of their actions which were motivated by their religious beliefs, but they were not condemned and exiled for their religious beliefs. Certainly Trotsky and his Red Army were probably very ham-handed and little discerning in their treatment of Russian Orthodox clergy and monastics who supported the White Russians. Once again, this is not evidence that they were systematically slaughtered as Christian martyrs and saints.
Thereafter, those who wished to advance in Soviet society needed to be members of the Communist Party. To do so successfully, they were obliged either to successfully hide their religious scruples or to abandon them altogether. And, of course, three generations of Soviet citizens were born and grew to maturity without benefit of clergy.
This is a long and perhaps questionable digression. Nevertheless, i consider it justifiable because dealing with such wild accusations is part of the experience of any atheist who is put upon by religious fanatics.
