You may be right. Still, if I were of the opinion that communist approach were the right one, I think I'd look to solve the branding problem. Music has no problem with defining new genres and sub-genres. Those with political ideologies could do the same.
the branding problem is being solved as we speak. newer generations are less indoctrinated by the cold war propaganda that created the branding problem. anarchists are developing new theory all the time, orthodoxy is antithetical to anarchism. the student group that organized the initial bus fare protests is considered autonomist, which is a newish strain of anarcho-communist thought that developed in the sixties.
Speaking of anarcho-communism, these protests have led me to do research on the anarcho-syndicalist strain of anarquism.
