This war is as clear as WW2 if you don’t see that then I don’t know what to say, it’s plain as day to most people.
I'm not saying they were saints but they were on the same moral plane of the Allies, wishing to set up buffer states instead of absorbing them fully into the USSR. Political repression was a real issue in the eastern bloc countries but it's no where near as bad as what the US, France, or UK did in the post war period with their colonies, segregation, bombings, or coups.
You’re thinking about USSR of 1980s when political repression and some hair cutting was the main issue. But USSR up to mid 1950s was a tad more evil to say the least.
And „debunking double genocide theory“ is fighting a strawman. Let’s talk how USSR started WW2 along with Nazis. Let’s talk Katyn or Rainiai. Let’s talk gulags. Stalin’s purges. Early USSR social reforms and consequences.
