Have to do what, indicate your disagreement with the Bolsheviks by concocting half-truths and/or outright falsities?
sigh Guin, I know how you feel about the Russian Revolution, but justifying repeating the same damn things you’ve said a hundred times before by saying you “have to” cry out against the injustice of it all just doesn’t cut the mustard any more.
Yes, there were firing squads and the secret police (CheKa) after October 1917. But they weren’t directed against the Russian population as a whole - they were directed against the people who wanted to restore the unstable bourgeois democracy of February, or push the clock even further back. Ddoes the name Kornilov ring a bell? Class warfare is never a pretty thing and to renounce the measures necessary to defend a new society from the old simply because they are violent is tantamount to suicide. Your precious Nikolai the Bloody used the same measures to repress challenges to the society he ruled, but to reinforce a backwards and reactionary society.
The gulags never existed under Lenin. There were prisons, certainly, but they were nothing like the slave labor camps that came into existence under Stalin.
Having said all that, back to the subject.
The Nazis, unlike anyone else in Scylla’s OP, were fundamentally a political expression of the sharp rise in class struggle across Europe in general and in Germany specifically. The extermination of the Jews was not their only goal, although that became their primary focus after they gained power. At the beginning they offered themselves to the German industrialists and the military as the only solution to the rising working class challenge stemming from the instability of the Weimar republic. Their intent was to make Germany safe again for capitalism by thoroughly smashing the organized working class.
While I do not believe that the other atrocities listed by Scylla are any less horrific, no other group that carried out these actions were portrayed as “enemies of democracy” like the Nazis were. They were (and I hope they remain) a unique combination of political and racial terror.
