I guess similarly, how do you actually deal with the "Individual people are not actually naturally equal in their capacities", problem?
Are these even questions that people who are Anarchists care about, or what?
I'm genuinely not trying to start a "thing" here, these are just questions that I feel like I've honestly just never got substantive answers on regarding Left-Anarchist political philosophy.
I would argue that the Soviets did a good deal to handle interpersonal prejudice as a major systemic problem in the political system; and similarly with regards to the ways that differences in personal abilities can negatively effect ones social & economic standing. Other problems, like social cliques coming to dominate/monopolize power & governance though, yeah I suppose they didn't do the best job of preventing.
I suppose I'm using the term as a shorthand for "reactionary persecution of social minorities". :shrug-outta-hecks:
cliques are a somewhat unavoidable aspect of human society i would argue. it would be nice if everyone could get along but we should plan for the fact they might not. In terms of avoiding cliques dominating governence I guess elections would be the only thing for it (they aren't 100% effective at that butt what can you do. We aren't pitching to replace a perfect system)
