It’s an oversimplified anarchist talking point against authoritarianism and the state. It’s noting the similarities between conservative talking points and auth-left socialist rhetoric.

Not to mention, the USSR was pretty socially conservative and that’s a big mark against them imo. Liberatory politics should liberate people, after all
