The article is a mess, but the root of the problem is that while the article presents giving “power to the people” and "dethron[ing] authoritarians" as goals of the left in principle, in practice what the left does when it comes to power is always the opposite. Leftists may talk about believing in democracy and freedom, but these principles are incompatible with the left's overarching goal, which is promoting economic equality. Since people are inherently different, the only way to guarantee economic equality is to use state power to control people. Of course, even where leftist principles are put into practice, such as in Cuba, North Korea, the Soviet Union, etc., the result still isn't economic equality, only a lack of freedom and general impoverishment of the most of the population.
