"This is as fine an example of the incoherence at the heart of leftism that I can think of. It is incoherent because it is nihilistic to the core. It is not rooted in any intellectually or morally defensible first principles, but is entirely subjective, arbitrary, and convenient. For what is the first principle of the secular left? We have been reviewing the deep structure of their ideology in recent days, and it all goes back to there is no God and we are his prophets! But this first principle has many disturbing and dysfunctional ramifications, which include the impossibility of transcendent meaning, the absence of any vertical order in the cosmos, and the devaluation of wisdom embodied in tradition (tradition representing the extension or "prolongation" of the vertical into the horizontal).
Therefore, when a leftist tells you that truth does not exist and that various texts are simply forms of domination rooted in the will to power, believe him, for this is the nature of the dark principality he inhabits. This is why I would never argue with a leftist, because they are so deeply and fundamentally illogical. Why try to reason with someone who has rejected the possibility of objective truth a priori? He is simply going to use whatever strategy or technique at his disposal to win the debate, not to arrive at truth, which isn't possible for him anyway. "
