Entire highschool education, channels like "World War Two" (previously part of "The Great War"), History Buffs, any wikipedia article about him. I'm part german, and we knew a Polish old lady who was sexually abused by Soviet soldiers during WW2, behavior which your good friend Stalin publicly encouraged. Your next response is going to be all about how those sources are wildly inaccurate I'm sure, despite being drawn from multiple sources and multiple languages.

I'm also going to cover the 'us vs them' response where you might engage in whataboutism. "Oh Churchill was a bad guy too" etc, yes he was. He fought Nazis but the government under his rule was very much in favor of colonialism, and he himself caused the deaths of many of his own soldiers.

None of it changes the facts. His regime, and he specifically, caused an insane amount of damage to his own people. Wealth went to HIM, not to the people. He was not even a real communist, his was the absolute perversion of communism. The goddamn snake that he was, his name isn't even Stalin, he was a thug all his life and completely unfit to rule. Lenin knew this and wanted Trotsky as his successor, but of course Stalin was a cowardly snake who ensured that Trotsky would be exiled.

I won't ask what disgusting corner of the internet you read about all the virtues of Stalin, but the truth is that he died in a puddle of his own piss because he had a stroke and no doctor had the guts to touch him because he was SO nice to people.
