The narratives in the media fetishize lone rebels "fighting the system" through symbolic acts such as heists or sabotage that never threaten the core machinery of the system.
This isn't a portrayal of anarchism. Anarchism is not a bunch of lone wolves, and it is not a system with no rules or organization.
I haven't seen all the shows you mentioned - are the characters explicitly called anarchists? Tbh it seems like you don't understand anarchism and are incorrectly attributing things to it.
I agree that media fetishizes individualism, but a much more plausible explanation is that doing so promotes Great Man theory, which is used as justification for capitalists hoarding wealth.
Meanwhile, Zapatistas are very much not doing great in Mexico
Changing the organizational structure to try solving problems their people are facing seems like a feature, not a bug.
start focusing on proven and effective methods of organizing instead
What methods are those, and how do they differ from the organizing that anarchists do?
Agree that retrenching isn't a sign of things going well, but surely you also agree that there are material conditions outside of the control of the Zapatistas that influence things not going well? E.g. drug cartels a problem in many parts of Mexico.
The new Zapatista structure is more decentralized, pushing more power to local centers: https://enlacezapatista.ezln.org.mx/2023/11/13/ninth-part-the-new-structure-of-zapastista-autonomy/
The organization of those local centers into larger federations is where communism and anarchism start structurally looking the same. The primary difference is that anarchists promote bottom up organizations, and communists tend to advocate for more centralized power.
Yes, anarchists don't organize around a vanguard party taking control of the existing state. Honestly, I think that's a bad thing to organize around.
Going on strike has historically been the best way to get concessions in the workplace, but union organizers don't organize around going on strike. Workplace organizing is listening to people's needs, giving support and reassurance, and empowering folks to apply the existing power they have to get concessions (even if they start small). Ideally, a workplace never actually goes on strike, and management realizes the workers hold all the power and concedes.
To me, that parallels broader political organization in two ways:
Regular folks want their own specific needs met, and do not care about a professional vanguard. You can try to convince them that they should care, or you can just work on meeting their needs (even if you start small). And that means not having a unified vision beyond "organize people and empower them to make their lives better." That may involve a vanguard party at some point, but only when it becomes a practical tool for improving people's lives.
... Anyway. I'm sure you're not convinced, and that's fine. I hope we can agree that both approaches have merit as ways of improving people's lives, even if we disagree on which is more effective in doing so.
