I’m not an anarchist myself but there’s definitely some tentative solutions to those problems. I don’t think it’s a problem with anarchism as an ideology, but with this specific type of online leftist who seems to be very preoccupied with being ideologically correct (while never reading theory) above actually carrying out meaningful actions. That’s the idealist part. The whole horizontal organizing and statelessness while still having ways to defend yourself (not sure about nuclear weapons) from hostile capitalist states I think isn’t idealism, it’s just a different way to fight capitalism from what we’ve synthesized on the “authoritarian” left.
