Newspaper columns and facebook are awash with people who use politically correct as a derogatory term and proudly announce that they make no apologies for being un-pc. Usually before saying something insensitive or even downright offensive.
The Collins English dictionary definition of politically correct is:
adjective
demonstrating progressive ideals, esp by avoiding vocabulary that is considered offensive, discriminatory, or judgmental, esp concerning race and gender PC
AIBU to try to be like that? Or is PC really the world gone mad and responsible for all societies ills?
