Our friend Mike provides us with an accurate overview of this pernicious Weltanshauung and rightly points out that it is by no means dead but (as I would put it) enjoys a healthy afterlife in those leftist seminaries called universities, but not only there:
I am convinced that ML [Marxism-Leninism] is alive and well in spite of the death of the Soviet Union. It has assumed new forms, discarded some ideas, taken some new ones on, but its spirit is healthy. Its spirit is essentially a collectivist one that does the following: It affirms that Man is infinitely malleable rather than limited by his nature, it denigrates individualism for the sake of collectivism, it de-emphasizes personal responsibility by making our behavior depend on things outside of our control, it relatives truth and morality by making them functions of group membership, it corrodes liberty for the sake of equality of results, it advocates the silencing of political opponents, and it is virulently anti-American (and anti-Israel, for that matter).Many characteristics of ML are present in vibrant abundance among a large number of political movements, particularly its hatred of capitalism and its emphasis on ‘imperialism.’ These political movements include the environmentalist movement, the Occupy Wall Street movement, the sustainability movement, the social justice movement, the social equity movement, the discipline of Sociology, nearly any academic discipline with the word “Studies” in it, and so on and on. ‘Political Correctness’ is a phrase that we rightfully use disparagingly to refer to any number of aggressively Leftist movements and tendencies that threaten the value of liberty.
You may well reject my path, but what is most important is that you do not abandon these four beliefs: There is objective truth, there is an objective morality to which you are bound, human freedom is real, and we must all be held personally morally accountable for our actions. These four beliefs will inoculate anyone against the twin poisons of collectivism and postmodernism.
