I’m sick of the term “politically correct” being used in the negative. The implication is that the person with the politically correct viewpoint doesn’t actually believe in their own position, but is just concerned with being sensitive, hip, diverse, inclusive, anti-establishment, or whatever. While there are people who take positions on things for the wrong reasons (e.g. to be on some bandwagon), the fact that a proposition is currently considered politically correct has nothing whatsoever to do with the truth value of that proposition .
It may be politically correct to suggest, for example, that the spotted owl is entitled to its habitat, and we all may be sick to death of politically correct bandwagoneering, but that has nothing whatsoever to do with deciding whether the spotted owl is in fact entitled to its habitat. Casting the issue as “politically correct” is a way of steering the discussion away from the issue itself and onto the character of the person holding the viewpoint. Political correctness has nothing to do with the price of tea in China (or spotted owls, or Nestle boycotts…)
Same with the way many right-wing commentators use the word “liberal” not as a description of political leanings, but as though it were an epithet to be hurled, an insult, an adjective just shy of “turd,” to be prefaced with adjectives like “bleeding heart,” “fuzzy,” etc. By casting “liberal” and “politically correct” as insults, discussion is tipped into the realm of name calling rather than issue analysis, and people are put on the defensive. It’s a technique for logjamming the dialog.
Sometimes “politically correct” is simply “correct” (and sometimes not).
