I believe that most of this can be solved with better concept of respect. For myself, I choose not to use words that needlessly incite fear in others, or words that create an environment that makes them fear for their safety, or also needlessly and knowingly makes them feel bad about themselves.
It does seem that respect is lacking more and more these days.
I think you are right that few people self-describe as "politically correct". Could you suggest a short alternative phrase that would improve Hanson's article? Or do you feel that word-choice aside, the referent itself does not exist?
OK, let's accept that. What's a better phrase that Hanson could use instead, and while still making the same general argument? I agree that "political correctness" is pejorative, but I also think there is some real underlying phenomenon that Hanson is pointing at. What's a less charged term that he can use to better convey his point without creating unnecessary offense?
I think the author describes it well, and makes quite clear that he is using Yascha Mounck's definition from a recent article in the Atlantic: "What people mean by “political correctness.” … [is] their day-to-day ability to express themselves: They worry that a lack of familiarity with a topic, or an unthinking word choice, could lead to serious social sanctions for them. (quotes, ellipses and brackets in original)
To write an article about this concept, he needs some short phrase. My guess was that the issue you had with the article was not a lack of clarity, rather a lack of charity. Like "Social Justice Warrior", or "cultural Marxism", or other terms that people use predominately to refer to ideologies they disagree with, calling it "political correctness" makes it hard to to have a productive discussion with anyone who doesn't already agree. As someone who seems to take offense to the current phrase, I was hoping you might be able to suggest a less offensive alternative that would be equally clear.
