Hmm…
For all practical purposes what does it mean to speak of being “politically correct”?
The right wing embraces a particular social and economic agenda. And then when the left wing challenges that and proposes an alternative agenda, they are accused of being politically correct.
Or:
The left wing embraces a particular social and economic agenda. And then when the right wing challenges that and proposes an alternative agenda, they are accused of being politically correct.
[“In reality” however it is almost always an accusation that is hurled by the conservatives against the liberals]
But it always revolves around behaviors that political/ideological factions either embrace or reject in any particular context.
More to the point [mine] are those who insist that if you don’t behave like they do than you are wrong. Whether folks want to insist in turn that if you are not “one of us” you are also “incorrect” seems rather moot.
It is merely understood that all rational men and women must behave as they do. Re God or Reason or Nature.
I call them “the objectivists”. But, sure, feel free to call them something else.
The bottom line however revolves more around the word “political”. Politics involves the actual distribution of power. In other words, it matters considerably less what/how you believe that folks ought to behave and considerably more who has the existential capacity to enforce a particular agenda.
Now, Trump and the Republicans will soon be in the position to enact [and then to enforce] their own “politically correct” policies.
But let’s not pretend that this not revolve around political prejudices that some see as “correct” and others as “incorrect”.
