""PC" has almost become a household word. In the 1991 Academy Awards pageant, a commentator joked that Dances with Wolves was "politically correct" (it shows Native Americans as decent and most of the white troops trying to exterminate them as bad guys). Since then, movie critics have sneered at films with anti-racist content, like Follow Me Home or Amistad, for their "PC" essence. The term has even inspired a major television show, Bill Maher's "Politically Incorrect" talkfest. Progressive people use the term without thinking twice about its reactionary function."
