Pretty uh, 'unique' trend of a 'mistake' when it has been the de facto course of action for exactly all of the historical 'socialists' within this bourgeois category (Stalinist, Stalinism/post-1921 Comintern-adjacent, etc.) to uphold an eerily particular and defined class interest in impeding, disarming and ultimately destroying (Allende was the one who (re)seated Pinochet!) the most advanced, threatening and independetly organised sectors of the revolutionary proletariat, don't you think?
Don't you also think it's time to polish up your Marx and integrate a real analysis of social relations to production so that you might better identify where your position truly lies?
I've found myself to be sympathetic to some of the communist left but I wouldn't
By the way, you would do well to read the whole text that came from (Pointblank!'s Strange Defeat), as well as the other two PDFs I've attached here; a small summary is interesting enough but to really see how hard Allende and his popular unity's bourgeois bullshit destroyed all true revolutionary activity you're going to want to see every detail of it. Disarming the independent workers' councils was far from the only damning thing he (or rather, the inherent nature of the parliamentary bourgeois State, we like to depersonalise politics as Marxists!) was responsible for.
