We'll like never know for sure how many people died because of Communist Regimes in the 20th Century, mostly because Red China kept no formal records of what happened during the Great Famine, so we're left with rough estimations that range from 10 million to 60 million.
But since Litwin loves to focus in on the Mongol Asiatic Asian Satanist Muscovite Stalinist Russia, it's worth pointing out that Stalin's death count is dwarfed by Hitlers, and it's not really even close.
We actually have a pretty good idea of how many people Stalin killed, because the NKVD kept rather meticulous records of their actions and Soviet demographics were regularly recorded. We know for example, that the Soviets killed 681,692 people during the Great Purge. Modern estimates for the Holodomor put Ukrainian deaths at around
4 million, while another 1-2 million died in the rest of the Soviet Union during the famine due to Stalin's insane agricultural reforms. Another million or so died due to forced relocations to other parts of the Soviet Union. Lastly we have the GULAG, of which 1.7 million died in. The issue with the GULAG statistics is that most of them died between 1941-1943, chiefly of starvation, when the USSR was in the middle of a war that saw most of it's agricultural areas under Nazi control, so the Soviets deciding to prioritize their limited food supplies for their non-prisoner population doesn't seem like a uniquely Soviet decision. In addition, the Soviets murdered some 40,000 to 60,000 Poles during their invasion and occupation of Poland.
So at the high end of things, we're looking at roughly 9-10 million deaths that can be attributed to Stalin. If we look at the lower end estimates, we get roughly 6.7 million deaths. So we'll say that Stalin was responsible for somewhere between 7-10 million deaths.
How many deaths Hitler is responsible for is difficult to determine, because there was a lot of overlap between groups killed (You can include Poles, Soviets, and Roma in the total number for those killed in the camps or not). We know for a fact that roughly 6 million Jews were killed by the Nazis. A total number of 11 million is usually given to account for the other 5 million people killed during the Holocaust, but that number varies. I think the easiest way to do this is take the total dead and subtract the Jewish element to get the best answer. We'll exclude battlefield casualties for the sake of argument about what constitutes killing and focus on civilians.
We know Poland lost a total of 5-6 million people during the war, Yugoslavia some 1.5 million, and the Soviets 27 million. Let's exclude military casualties (60,000 for the Poles during the invasion, 300,000 Yugoslavs killed in action, and 9-10 million Soviet military casualties). But that number itself is suspect; 3 million Soviet soldiers died in POW camps, not the battlefield, starved to death by the Nazis. It also brings up the argument about how you define Partisans, as soldiers, or civilians, but we'll shelf that argument for now. Minus military casualties, Soviet losses were roughly 16-17 million people, either killed directly or as a result of the Nazi invasion. So we're looking at nearly 5 million Poles, 1 million Yugoslavs, 16 million Soviets (and when you include murdered POWs, 19 million) for a total of 25 million people killed by the Nazis. And that's not getting into the millions of Jews, Roma, and other minorities that were citizens of German satellite states that were also murdered.
Long story short, the Nazis killed more than the Soviets. Cue Litwin screaming about Asian Mongol Muscovite Satanist hordes.
