"A bad word whispered will echo a hundred miles." Chinese proverb
"Can't we all just get along?" -- Rodney King
Where I come from, " PC " ranks high on the list of important character traits. It's viewed as a sign of a good upbringing. It indicates a balanced, collected, well-adjusted and self-assured personality type.
"Treat people the way you would want to be treated," is something that my parents drilled into me and my six siblings from the moment the "brat" in each of us began to emerge.
Of course, they were right. And it was a lesson that many of us had hoped the world's societies would have long ago absorbed. Whether it's a high-stepping, self-centered, trust-fund blue-blood, or a disabled homeless vet on a street corner begging for change, everybody wants to be treated with dignity and respect. That's a point I've heard made by practically everyone I know virtually every time they feel that they've been denied such treatment in one way or another.
Perhaps that's why to me, the initials "PC" have always stood for "Polite" and "Courteous."
