it’s hard to keep your brand new society when the tanks show up immediately. this is not a weakness of anarchism or any political system.
you can look to rojava and the zapatistas for an example of defense that has worked for years despite long odds.
they did it for years in a significant territory. the state had no power there during that time. that was a success, even if it was rolled back by a nationalist military (supported by nazi Germany) and undermined by authoritarian communists. also, again, there’s rojava & zapatista Mexico currently, plus other historical examples.
why are you demanding an impossible standard of perfection before you are willing to fight for a better life for yourself and everyone else? that’s just doomerism and it serves the capitalists.
the point of anarchism is not to control the state, but rather to stop having one. for the territory that made up anarchist Spain, that was successfully achieved. it’s no weakness of anarchism itself to be defeated militarily; all kinds of societies have been defeated militarily.
anarchism rejects nations, so why should its success be judged based on national borders? a successful society is av successful society
not every direct democratic system is majority rule. there are lots of ways to make decisions! remember, we don’t need perfection, just something better than the tyranny of the minority we live under now. we can improve from there.
anyone seeking to sabotage decision making in bad faith can be handled however a given commune has decided to handle antisocial behavior (rehab, restorative justice, offering therapy, etc).
