Adam Curtis, in his movie HyperNormalisation, talked of a theory that this kind of activism disappeared around the 70s and 80s. It's the kind that requires banding into groups, to a significant extent giving up individuality. According to the theory this is also the death of politics: the hyper individuality took away politic's power and left only spectacle and populism. The way he told it was that the hippy revolution back-fired: the look-within insight turned into consumerism and heightened individuality. My retelling is a bit scattered. The movie is well worth a watch.
