You keep talking proof, then show me some. I have about had it with your little game. Prove this, prove that. Well, guess what, by the laws of science and nature, it is impossible to prove that Stalin ever even existed. All that can be proven in history is the coming of a present existence. How it comes to exist as so, is impossible to prove, only that it came to exist as it does.
In this respect, absolutely no historical events or people presently dead and decayed can be proven to have existed. This includes WW II even.
We judge history according to footage, artifacts and records made by people, not by facts. All anyone has to go by are these things.
I can tell you that Hitler was a fun loving monk who gave every penny to help others and adored Jews, and you can never prove otherwise. We believe otherwise because their are no credible historical accounts that he was, while their are extreme historical accounts that he was a barbarian.
Same for Stalin. All these things some of you claim about him being a good guy, no one can prove otherwise, but their are extreme historical accounts, footage and evidence that he to was a barbarian, not what you WANT him to be.
The people who claim otherwise alike yourself offer nothing of valid historical accounts, artifacts, footage etc. to show otherwise. Only flawd statistics.
