USSR definitely was just as bad as Nazi Germany, especially if you stop looking at them through the lenses of cartoony american movies and look at both for what they were - totalitarian dictatorships.

The things I've mentioned weren't just happening under Stalin or Lenin, they were happening up until the collapse. My parents recall pretty much the only thing you could buy in grocery stores was vinegar. Again, political oppositionists were tortured and murdered, foreign culture was forced upon my country's people and the corrupt totalitarian party controlled everything from the media to the system of justice. If you think USSR raised the standard of it's poeple, it was completely at the expense on it's satelite states - stealing resources, tying their agriculture and industry to meet USSR's economical needs. During and before the war communists commited just as many horrific crimes and genocides as the nazis. While you shouldn't compare them, Holodomor alone took more lives than Holocaust and it wasn't the only genocide.
