I ran across the following through our good friend, Google.
Message 2: "PC" summary (1996 version)

From: "James T. Myers"
Subject: "PC" summary (1996 version)
As I suspected, the origin of "PC" has been discussed before (including,
apparently, on this list, in 1994). I will only add a few tidbits which
were sent to me by my many correspondents. First, here is a reference:
Perry, Ruth (1992) "A short history of the term politically correct" in
Aufderherde, Patricia (ed.) _Beyond PC: Towards a Politics of Understanding_.
I am not able to check this myself right now, but apparently it promotes
the Maoist origin theory, which seems to be well-supported by the personal
anecdotes I was sent. However, Dennis Baron provides evidence suggesting
that the term is still older. It's possible that the 1947 Nabokov
citation and the 1936 citation were borrowing Marxist-Leninist terminology
(with the 1793 citation a fluke), but they certainly can't be Maoist.
Perhaps these extra-early citations were influenced by the same sources
that influenced Mao, but that's going back a bit too far, I think. The
phrase didn't take on a life of its own, apparently, until it was picked
up by radicals in the '60s. Frederick Newmeyer's observation of a shift
in usage by leftists (from politics to individual behavior) is also
supported by anecdotes I was told. The usage of "PC" that I encountered
in college in the mid-80s was then a still later, sarcastic, usage. It
was this usage that was then modified and spread to the mainstream by
non-leftists. Hence (and feel free to disagree with this -- I won't
defend any of it):
(0) Compositional semantics usage: "PC" = "politically" + "correct"
(at least since 1793)
(1) Marxist-Leninist usage: "PC" means to conform to official policy
(ca. 1930s?)
(2) Maoist usage: the same
(ca. 1950s?)
(3) North American Maoist usage: the same
(ca. 196x?)
(4) later NA leftist usage: "PC" means to behave in an appropriate
fashion, even if there is no official policy at stake
(examples of this usage found as late as mid-80s)
(5) leftist/centrist sarcastic usage: "PC" means to be too
dictatorial about appropriate behavior in others
(earliest anecdotes go back to 70s, perhaps dominant usage by 1985
-- still may be used this way on occasion, even in mainstream press)
(6) current usages: see your local media
The only other interesting thing I can say on this is to pass on the
observation of Miriam Meyerhoff, who, at university in New Zealand ca.
1981, heard the phrases "politically unsound" and "politically sound" used
according to usage (4), along with the abbreviations "PU" and "PS". Just
to add a bit of lexical variation to your helping of semantic drift.
Anyway, thanks to the following correspondents: Karen Baumer, Elissa
Flagg, Warren Frerichs, Dorine S. Houston, J. P. Kirchner, Joerge Koch, Tom
McClive, Miriam Meyerhoff, Janice Rothstein, Kevin Russel, Marilyn Silva,
