To be fair, the establishment dictionary definitions of those words are about as useless as the urbandictionary definitions.

Even the Wikipedia definitions have their issues, because they’re written in the register of liberal/bourgeois hegemony. Just look at “totalitarianism”: it’s Arendtian horsepoo theory. Hannah Arendt came from a wealthy family and so unsurprisingly was anticommunist, and her work was funded & promoted by the CIA.
