One of the things I love about anarchist thinkers is that you don't have to pretend they were infallible idols. There's a little bit of mythologizing that goes on among anarchists, but most of us acknowledge that as a rule they were insufferable people naturally replicating the trauma they experienced from the political systems they lived under onto others. If someone is like "Bakunin was an antisemite" you can be like, "yeah, and fuck him for that. Fuck all antisemitism. But he hated the state most of all, so lets talk about why."
I don't think that's a good thing -- it has definitely been an obstacle in anarchist organizing, and we wouldn't say "Be careful with each other..." if we didn't need to be reminded. Maybe if there was an anarchist Mr. Rogers, we'd have automated transgender space luxury communism already.
No Gods, no masters also means no anarchist gods or masters.
It's this potentially an instance of separating the work from the man? Picasso was a pretty shitty man, but recognized art. They could still be "correct," if there even is such a thing, but they didn't necessarily act according to their ideals.
