I read a book about the Stalinist gulags and it said prisoners had to sign Stalin a birthday card every year! Can you imagine that? How horrible! Okay, it was a fake, it totally didn't happen. The author made it up. But you could imagine it really happening in the Stalinist universe.

You couldn't just simply imagine the same thing with Nazism though. That's why, according to these facts, Stalin is objectively worse than Hitler.
