The term “political correctness” wasn’t used much, if any, when I was growing up in the 80s. Back then, we called “political correctness” by something else.
We knew it as “good manners.” We were taught certain things were unacceptable to say and/or do.
What I really want to know is: Why do certain Americans hate “good manners” so much? Why is it they protest when others tell them that they are exhibiting “bad behavior?” Were you people not taught this stuff growing up? The real scary part: these same people behaving badly grew up around the same time as I.
