"at first?"
(*cough*) "Was you _dere_, Fritz?"
Well, historically, "politically-correct" was, as best I can recall,
a phrase used by Marxist(-Leninist?)(-Maoist?) theory hacks to
dissect or deconstruct utterances (you name it, movies, PhD theses,
*any*damnthing) of which they disapproved. And there were real
consequences if you didn't measure up...
To have published something not-politically-correct was to have put
oneself at risk of demotion, being passed-over, reeducation (in the
paddies or gulags) or adjudication as (politically-)insane. Sometimes
one simply disappeared and/or was written out of the encyclopedia just
like the Tu-144.
I'm sorry, but long before the phrase was sanitized by lefties, the
phrase had a lot of the same weight as "pure Aryan stock", and yet I
don't see any Nuremberg trial being scheduled for the guilty still
living.
*cough*, again.
Now, as to your other point: Doctrinaire *anything* is *always* a
worthy candidate for inspection. Left, Right, up, down, in, out...
Be well,
