Political correctness is a term I often see bandied about -- particularly on social media and "below the line" comments on news articles. Usually whenever issues of racism, sexism and other inequalities are raised.
Merriam-Webster defines political correctness as "conforming to a belief that language and practices which could offend political sensibilities should be eliminated".
However, the term was first associated with the Stalinist regime. 'Politically correct' was used disparagingly to describe those whose loyalty to the Communist Party overrode compassion and judgement.
In the 1990s, it was adopted by US conservatives to criticise left-wing policies of affirmative action. These days, it seems to have evolved into a slur against those involved in protecting disenfranchised groups from abuse, prejudice, exclusion or misappropriation.
There are many who try to encourage respect, equality and social justice by promoting celebration of marginalised cultures (such as protecting te reo in New Zealand), gender-inclusive language, diverse workplaces and fair portrayals of minority groups in media. But there are just as many times the phrase 'PC gone mad' rears its ugly head.
