even "classical" anarchism had different branches (schools?). We shouldn't treat it as one monolithic movement.

Today anarchist movements are scapegoated as "ultra-left", to pull frightened masses towards extreme-right (banalised as right) but anarchists, refusing to participate in the government, had no place in the left-right seating of politics.

What do you mean by "post-left anarchy"?

edit: i was reading "Les Nouveaux Anarchistes » by Francis Dupuis-Déri. At the end of the book he mentioned Bob Black. I started reading one of his from https://theanarchistlibrary.org/ and now i know what you mean by "post-left anarchism".
Not everybody is aware of who Bob Black is and the terms he invented.

i had a copy of "The Abolition of Work", printed as a pamphlet, handed out at a squat. It was light and fun. "Post-left" doesn't mean much when you're not into Bob's writings: "What is post-left anarchism? I’m not sure who coined the phrase, but it looks like I did."
