My opinion BTW is that "political correctioness," as the term is most commonly used, occurs when a person is confronted about something they said that they cannot then justify within the confines of then-acceptable societal norms.
It's basically used as a term for being called out for being outside of what is considered to acceptable social behavior at that time. And who likes that? No one, of course.
Now, REAL political correctness is when such 'acceptable behavior' is directed by political authority figures. For example, when Trump attacked the kneeling NFL players by falsely accusing of disrespecting the military, that was actual political correctness.
But if you say something stupid and disrespectful in public and someone else calls you a nasty name for it, or if you write a ridiculous memo discussing at great length about how half your co-workers were somehow born incompetent for their jobs and your private sector employer shitcans you for it, that isn't political correctness. It's consequences.
