Postmodernism argues that logical fallacies are just as valid an arguement as an argument that is logically sound or an argument that emploies pure reason.
So if a retard says, "x^4/x^2 = x^2" and I say, "I don't like math! It's too hard! Math is stupid!" or, "Haha, fucking retard! He is obviously wrong because he is a retard." Then we are both equally true? This philosophy is bullshit and a childish view on the world. It asserts that, "We are all winners." Yet, illogical bullshit is not as true as pure reason, and without reason: we are no different from animals. Postmodernism is also a life denying philosophy, they view objective reality as unknowable. This is false.
