Having recently been subjected to another generic rant against the evils of political correctness, I want to try understanding what the problem is. The claim is that those nasty politically correct people are trying to “introduce ambiguity” and “rearrange the language to avoid solid fact”. I would agree, without question, that those are bad things. We want the language to be accurate and precise.
Consider what would have to be the prototypical example of political correctness: replacing “black” with “African American”. The term black is not accurate; the people in question have skin tones ranging from dark brown to light tan. Trying to label by skin color inherently causes ambiguity, because other ethnic groups overlap the same range of skin colors. “African American”, on the other hand, is right on the money. We’re trying to describe people of African heritage who currently live in America.
An even clearer example is replacing “Indian” with “Native American”. “Indian” was a horrible misnomer to begin with, the result of utter confusion and nothing more. Centuries ago it might have been usable, but only because no one from India was moving to America. Nowadays we have a sizeable population of the group that’s correctly labeled “Indian”, so we’re at risk of having two contradictory meanings for the term. “Native American”, on the other hand, is exactly accurate and erases the ambiguity.
The most common example of political correctness, though, is simply changing the suffix “-man” to “-person”. Postmen are now postpeople, salesmen are salespeople, and so forth. Why? Well, back in the day, these professions were entirely male, or close enough. Not anymore. Now that we have sizeable numbers of women in the workforce at all levels, the change makes sense. It’s extremely awkward when you have to give a woman the “Businessman of the Year Award” or something of that nature.
