I don’t mean to be so harsh, but the old marxism has no chance in its legacy form.
Remaining faithful to the core idea as neo-communism sit down and rebrand the whole legacy. Take Last and First Men as a template from Preface to Conclusion and create a new form of activist socialism/neo-communism. Try it as an experiment. Focus on the years of the 1840’s as a saga, and skip marxist theory.
