While I don't wanna get more into this debate, I should one more time state that reducing Marxism to "inhuman Marxist societies" is ad hominem and your argument doesn't have any value to me. Also you used/coined a word "state socialism" which to me is an oxymoron as I cannot conceptualize socialism that is not stateless.

Marxism may be reductionist or wrong (and it is) but it is almost by design wrong. Darwin was also vastly wrong and ignorant (he didn't even know genes). There is a very rich academic literature on Marxism, that is not written by laymen (like Stalin who I doubt ever read any Marx). Similarly, modern biology is almost all about evolution regardless whether Darwin's original ideas were accurate or not, they found their own way. Marx is outdated in a very similar fashion Freud or Darwin are outdated. Just 'cause some inhuman eugenics people thought we can apply "Darwinism" to kill people doesn't make Darwinism inhuman (unless you think it does, but I don't think so).

This sort of reduction wasn't what I was going for. To me Marxism is a tool, just like any other tool. It gives me a clear framework to conceptualize and analyze things, using a very similar analysis Marx used in the German Ideology, Capital etc (which people sometimes say reversed Hegelianism, but this is not very accurate). It's about when you observe the world what you see in abstract. Of course, in real life people still do stuff independent of their financial situation etc. This is not relevant imho.
