According to my research, "political correctness" began in the 1980's as a reaction to ultra-conservative groups using disparaging language when referring to multi-cultural, affirmative action and feminist activities.
The movement has since crept into all aspects of life. It is like having to learn a second language. Now, the following new appellations apply:
tree hugger-environmental activist
gas station attendant-petroleum transfer engineer
prisoner-client of the correctional system
So, for all my years of ranting at the "left" for the political correctness movement, I apologize and stand "corrected". It was the "right" that was wrong.
