Sorry, but claiming that just shows that someone didn’t engage at all with anarchist theory.
Edit - addendum: even if this wasn’t true back then in Engel’s days: Still quoting him today ignores all that anarchist theory on power that happened since then.
I have, I used to lean more Anarchist, until I read more Marxist theory. Concepts like ParEcon were extremely interesting, and could be applied to both an Anarchist system or a Worker State. I am aware of Anarchist principles of horizontal organization, and I think they are quite beautiful, but I am also aware that Anarchist critique of Marxism falls flat almost all of the time.
What kind of Marxism? Marx’s Marxism, or that body of theory by his followers that even Marx denounced, i.e. ML, MLM, etc.
Anarchist’s analysis of power has been spot-on ever since Bakunin predicted the bureaucratic dictatorship that Russia became under the Bolsheviki.
How exactly would Marx denounce Lenin? Or Mao? That’s a supremely goofy statement.
Bakunin was not correct in analyzing power. If saying “states have issues” counts as being “correct” enough to only approve a system that has only ever lasted a few years at a time, you’re intentionally missing the forest for the trees. The USSR was by no means perfect, but it was history’s first true Socialist state and managed to prove that Socialism does work.
The problem with anarchist theory is that it demonstrably doesn’t work. A theory that can’t be put into practice is not worth the paper its written on.
