Because in the 1960s, there was a mutation in Marxism as an ideology. Because white male workers in usa and western Europe the 1950s and 1960s were satisfied with everything and did not want any revolution, because they enjoyed the prosperity of that time. Therefore, the left has mutated into the new left. Now they are not interested in the class conflict between workers and the bourgeoisie or the conflict between the poor and the rich, because from their point of view, white male workers have failed them, because this group is easy to satisfy. But women, racial and sexual minorities, have become the new revolutionary element of the new left, and they have taken the place of the proletariat (factory workers), because fags, foids, and niggers are greedy and insatiable, and therefore they can never be satisfied, because once they get one thing, they immediately demand more benefits, more quotas, and more privileges.
