Liberalism arose from “enlightenment thought” and basically said that all humans are equal, therefore state legitimacy comes from the consent of the people, and therefore there should be a set of laws that guarantees everyone’s rights and gives everyone a say in how society should be run

*This was only applicable to western European nations. Liberalism was the moral justification for the enslavement of the world under colonial and neocolonial schemes. Since Europe was said to be the cradle of morality and values, the rest of the world were barbarians who were deemed needing stewarding and European intervention.

Some leftists theorized the state should be violently overthrown in order to install themselves as dictators and therefore solve the social question by directly redistributing wealth to the poorest. The most important of these is Lenin

This is very much not true. Leninism is a theoretical development of Marxism applied to preindustrial nations. Marx theorized that the socialist revolution would stem naturally from developed industrial nations, but Bolsheviks saw the revolutionary potential not only of the industrial workers but also of the peasants. Lenin led a democratic vanguard party until his death, but understood that a socialist project in construction will have interference from capitalists both locally and abroad, and needs state repression of said interference in order to be able to carry out the goal of redistribution of power to the people because capitalists won’t just give it away.

Stalin, who cemented his dictatorship and took over a number of countries through military force

I think you misspelled “eliminated fascism from Europe and saved tens of millions of lives from Nazi extermination”. It wasn’t done personally by Stalin, but by the socialist project of the USSR as a whole.

You did a great job disregarding the colonial history of the west and the implications it had for billions of people in the global south.
