You think anti-(fascist-)capitalists have no better suggestions than dictators from 40+ years ago?
It would seem that they don't. Their suggestions, when they exist, are based on a childlike naïveté that can be justified only with near-complete ignorance of both history and human nature.
Conflating opposition to capitalism and opposition to fascism is a good example. The sad thing is that you don't have to go very far to the right before you encounter stupidity of comparable magnitude.
