You’ll see anarchists praising Rosa Luxemburg, who if they had actually read her writings – they would see that she was very clearly one of the “authoritarian” socialists that they rail against so much.
You see them praise the Black Panthers, who were supported financially by the DPRK and aligned themselves with the Juche ideology of Kim Il Sung.
They even praise Thomas Sankara, who purged anarchists and arrested syndicalists.
If these people had succeeded, i have no doubt in my mind that anarchists would call them “tankies,” they would call their experiments “capitalism with a red flag.” And I also have no doubt in my mind that if the October Revolution, Chinese Revolution had been crushed, they would hail Lenin and Mao as proletarian heroes.
They’re pretty much more liberal ultras. They bang on about this wonderful utopia and tear down any attempts at socialist revolution or maintaining a workers state. And not only that, but they don’t put in the needed work into building towards revolution or increasing class consciousness among the working class. They’re entirely fine trying to build cooperative farms or doing performative mutual aid.
