False Leftists will keep getting badly humiliated by rightists so long as they keep trying to claim credit for Western knowledge, since the very attempt to do so is an affirmation of the value of the knowledge being claimed:

Only the True Left approach of despising Western knowledge can defeat rightism. Instead of trying to claim calculus as of non-Western origin, we should be pointing out that it was calculus that made possible the engineering required for the Industrial Revolution (which, predictably enough, arose from the same civilization that invented calculus, duh!) which everyone already knows has irreparably harmed the environment:

In general,
knowledge is power. The drive of Western civilization to endlessly accumulate knowledge (and to always seek practical applications for it) is nothing more than a reflection of its desire for increasing its power. This is why Western civilization is uniquely dangerous:
