Credit to Crusader Knight http://www.crusaderknight.blogspot.com/ for this excellent definition of the term, Political Correctness.
The following is the 2007 winning entry from an annual contest at Texas A&M University calling for the most appropriate definition of a contemporary term. This year's term was 'Political Correctness'.
The winner wrote,
'Political Correctness is a doctrine, fostered by a delusional, illogical minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.'
