Interesting concept, Scott.  I have not read the book since the early 70s', so my memory might be a bit off.

As I recall, "newspeak" eliminated nuance,  subversive phrases, and changed the meaning of other phrases.  It also changed the way certain things were presented.

We have similar situations of "newspeak" in the way many debates are framed by language.  As an example (among many), the abortion debate.  One side presents it as "pro-life" and the other side as "pro-abortion", the other side as "pro-choice" and "anti-choice".

One of the amusing things in newspeak is the use of good and ungood.  No need for great, swell, exceptional, awful, horrendous, etc.  Just black and white (although I seem to recall the book addressed the idea of black and white as "blackwhite").

I find it ironic that you use the phrase "political correctness"  in making your point.  With my understanding of "newspeak", you are using a phrase that used to mean a certain concern for a particular group as the pejorative statement it has become over the last decade or so.  Thus, it seems to me you are using "newspeak" yourself.
