It Is Vital to Understand that Political Correctness Is Utterly and Completely Immune to Evidence; the Reason that PC Is Absolutely Evidence-Proof Is that It Operates at a Wholly Abstract Level

It is vital to understand that political correctness is immune to evidence – and I do not mean resistant to evidence, nor do I mean blindly dogmatic such that PC requires an overwhelming weight of evidence to be convinced; but I mean utterly and completely immune to evidence such that unanimity of incontrovertible evidence against PC is still insufficient to induce significant re-evaluation.

This is important to realize; since it makes clear that time, energy and personal resources expended on trying to convince PC advocates with evidence is just so much time and energy down-the-drain and lost--precious resources that could potentially have been expended constructively elsewhere.

The reason that PC is absolutely evidence-proof is that it operates at a wholly abstract level.

But the reason that it superficially appears that PC might potentially be open to evidential refutation is that, although abstract, PC is concerned exclusively with material proxy-measures of its abstractions.

That is the distinctive move which sets-apart PC from any preceding ideology.

Political correctness operates on the assumption that an abstract system of allocation is intrinsically superior to the lack of such a system; and the details can be worked-out in the fullness of time. . . .

My point is not that abstract systematic altruism is a means to some kind of end, but is an end in itself.

This is why effectiveness is of no interest, outcomes are of no concern and evidence has no relevance.
