There...I said it.
I will face certain disagreement, but I care not. 'Political correctness' is a feeling. It is ethereal. It is unmeasurable. It is also not intellectually mature discourse.
But it has pervaded our discussions of all things cultural and political, and used as a weighted pejorative....instead of argument on merit.
It is typically employed by the right, to explain away those paradigms they disagree with...most often [or indeed solely] against the left. Yet those on the right who employ this tactic, fail to realize that 'political correctness' exists as surely on their end of the spectrum as it does on the opposite.
For the reasons initially stated. It is a feeling. Why then, would a socio-poltical subset who usually derides basing assessments on feelings, employ the very tactic they make caricatures of?
