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?
I think that this debate would be more useful in the context of an actual revolution, since the anarchist vs Leninist argument is a practical argument, not a matter of philosophical difference. I just asked these questions because I want anarchists to think more about the practical problems involved in revolution, and I think that most of their solutions would be compatible with Leninist ones.
