This is mostly a serious question. Also, not for the tankies/MLs. I already know what your answer to that question is. I may not always agree with you on everything, but you do have an answer that if the conditions became right, could actually work.
No, this is for the type of anarchist completely against the wall, gulags, seemingly any amount of getting hands dirty. What is the solution to those types of people? There are so many of them in the US, a lot of which are heavily armed, that they could easily topple a socialist system, and even if they didn't do that, their existence would be incompatible with any marginalized group living their lives, since they love to harass them at best, outright murder them at worse. So what's the solution? Anarchists often seem to avoid this, seemingly believing that if there was a socialist or communist society, they would just say "aw shucks, guess I was wrong about that. Guess I'll no longer be racist or xenophobic!"
So am I missing something, what's the answer?
Depends on the type of revolution. A syndicalist one would have new systems in place that take over completely indipendant of the old state. It would be increadibly hard to overtake democratic workers unions, especially without state support to crush their resistance. That approach requires strong unions though.
A more classical Ancom revolution spawns from a very chaotic situation were a lot of shit is happening really fast. A military response to it is much more likely in the early days and then (if it does not fully succeed) when the reaction kicks in. Still, people are reluctant to shoot their own. An anachist revolution in a third world country with American presence would be violently crushed by the US they barely hesitate when it comes to shooting their own as is.
The beauty of the Anachist approach is, that liberal democracies can not eadily justify a military intervention. They happen too fast for the maufacturing of consent to keep up and reframe it. And the Amerikkkans are good at organising coups, but you can not coup anachism.
