Forced labour camps and secret police organisations were pretty ubiquitous. The Tsars had The Okhrana, forced labour camps and political repression (Lenin, Trotsky and Stalin had all been exiled to Siberia). The Checka and Gulag were the Bolshevik versions of the same thing. Russia had the White Terror... and then the Red Terror. It all fucking sucks but the point remains, Stalin took things to new levels of psychopathic insanity where we start hitting 10s of millions of excess deaths.
If you don't like Gulags, then bear in mind they were created at roughly the same time the US setup forced labour camps in Haiti that led to 1000s of deaths and extra-judicial killings. Not something Americans talk about much. Should Woodrow Wilson be compared to Stalin too?
