It began with intelligent but still naive people in universities and colleges with good intentions. Hell is paved with such intentions. Despite being intelligent none of them decided to heed the many warnings against political correctness expressed in a novel written in 1948 and published in 1949. The book? Why its 1984 of course by George Orwell.
Well it really is a case of our politicians allowing political correctness to get out of hand. It has become a useful tool for them. Someone starts asking awkward questions about water supply, sustainability, overpopulation, immigration, etc just trot out political correctness to shut them up. What's more, you can get high school, university and college kids on side who have been indoctrinated into blindly following the political correctness trail. You want an important issue not to see the light of day? Use political correctness. We are made so sensitive to the needs of others that we forget our own needs. By the time it dawns on us that our needs and their needs are the same the power brokers have some other shiny new bauble to dangle before us.
Kathryn1000 if you are a politician who has been making a nice living supporting political correctness or a teacher of any stripe without any street smarts whatsoever of course it hasn't gotten out of hand and never will. We can always blame bad things happening on other things. Talk straight and honest and we might actually solve problems. But that is not the way of political correctness.
