... was an ideology that gave 200 million of people universal healthcare, universal childcare, public housing and increased luteracy rates but took away democracy and national self determination, unleashed genocide and allied with literal Hitler
How did it take away national self-determination exactly? The Soviet model regarding self-determination was definitely better than what any other nation had. I probably don't have to mention that Lenin wrote a whole book on national self-determination, defending the right to self-determination on the condition that it does not harm the socialist project.
Although one may call it superficial, a mere formality no indicator of self-determination in the Republic, it is remarkable that the Soviet ruble had 15 local languages printed on the banknote.
Most ideologies are terrible in those regards. The various forms of democratic capitalism have been pretty big on genocide and oppression too. Most of them were were pretty unconcerned with Hitler until after the marxist-leninists were already fighting him.
Not sure what point you're trying to make.
