what was the difference besides them not liking each other? Both Marxists and Nazis were violent racists (I could tell you some really racist stuff Marx or Che Guevara said) and even homophobes, they hated religion, they both wanted to rule the entire globe, they both killed dissenters, they both required revolutions to get in power, they both took the mob by promising to unify the people into one class and one group of people (and someone has been saying stuff like that recently in America), and they both have dictators that were the richest and benefitted the most from the systems.
The only thing I can see being different from the two is money distribution. However, communism is literally the worst plan you can even get for money distribution, given that it takes from the rich and gives to the government, who owns all property and hounds all the money. Since you really can’t get more hostile to the people than that in terms of money, if anything, Communism is even worse than Nazism, unless Nazism uses the exact same system, which I will admit I don’t know. But this point still stands. And I hate Nazism just as much as any liberal does. Matter of fact, my hatred for communism is based on the same principles that cause my hatred for nazism, and the Italian Nazi leader Mussolini was inspired by Vladimir Lenin, who was one of the worst human beings to ever roam this earth.
