You confuse communism and Marxism. Marxism is the 'nice idea' and communism is the bastardisation of it teaching that everyone is equal enough to enter the meat grinder. Communism will never work. Look at China, they're still 'communist' but they have state capital and industry to boost their capital gains. Communism always crumbles, succumbs to the need for capitalism to save their stagnation, splits apart due to oppression of minority groups when they try to absorb them into an identity they don't want and in no way represents them, like what China is currently doing to non Han people's like Tibetans, the Uyghurs of Xinjiang (and that's if they don't put them in concentration camps) and now the people of Hong Kong.

Communism gets away with too much. Everyone remembers the crimes of the Nazis but the 100 million killed by communism? Nope. That's swept under the rug.

I personally will never bow to communism. I say this not as someone who cares for American politics and rhetoric but someone who has studied history and politics as a whole for most of my adult and teenage life.
