Why do conservatives and (some) libertarians cringe and react negatively to political correctness? I mean by political correctness “language, policies, or measures that are intended to avoid offense or disadvantage to particular groups in society.” Further, critics of p.c. use the term “as a pejorative, implying that these policies are excessive,” not to mention the language and measures of p.c.-ness.

There are several reasons to reject p.c.-ness:

1. It is often condescending toward the identity groups it is meant to protect and advance.
2. It is meant to hide the truth about common characteristics of such groups.
3. It implies that those persons who don’t join in p.c.-ness are racist bigots with minds that are closed to reality (which is exactly what 1 and 2 say about proponents of p.c.-ness).
4. The policies and measures that flow from p.c.-ness usually go beyond “avoiding disadvantage to particular groups” to confer advantage on particular groups.
5. Such policies and measures are therefore anti-libertarian, and often are costly and ineffective (even counterproductive).
6. Such policies and measures tend to penalize persons who have had nothing to do with any real disadvantages that may have befallen various identity groups.

I can’t speak for conservatives as a group — though they should be a “protected group” (I write sarcastically). But I can tell you that my rejection of p.c.-ness is based on all six of those reasons. And the sum of the six is a devastating attack on social comity (or what’s left of it), even-handed treatment of all persons under the law, freedom of speech, freedom of association, property rights, and the economic well-being of the nation. Other than that, there’s nothing wrong with p.c.-ness.

Whatever merit there is in p.c.-ness, it is canceled by the bad odor that surrounds it. P..c.-ness is a variant of crying wolf: The more often it’s invoked, the less believable it becomes. There’s a corollary: The more people who require p.c. treatment, the fewer people who are left to be blamed for the conditions that p.c.-ness is meant to remedy. Or, if almost everyone is a “victim,” almost no one is a “victim.”

Unless you believe, of course, that straight, white males of European descent are to blame for every bad thing that has befallen every other identity group. Or unless you believe that it’s simply “unfair” for straight, white males of European descent to have been so dominant for so long in so many fields of endeavor.

Was it “unfair” of Newton and Einstein to have been the greatest of physicists? Was in “unfair” of Abraham Lincoln to have been the president who conquered the South and thereby put an end to slavery? Is it “unfair” that there seems to be something in the genetic makeup of East Asians that gives them higher IQs on average than whites, who have higher IQs on average than blacks? (Why aren’t whites complaining about the “unfairness” of the distribution of IQs?) Is it “unfair” that (in the United States, at least) whites, who are on average smarter than blacks, earn more than blacks on average? If that is “unfair,” why is it “fair” that the NBA is dominated by black athletes whose IQs are lower than the IQs of white physicists but who earn many, many times as much as white physicists do?

The problem with “fairness,” which is at the heart of p.c.-ness, is that it is a reality-free concept. It doesn’t take account of the facts of life, such as those alluded to in the preceding paragraph. It assumes that differences in outcomes (e.g., relative earnings, literary fame, scientific achievements, political advancement) are due mainly to one’s membership (or lack thereof) in an identity group. P.c.-ness leaves no room for reality. It leaves no room for individual responsibility. It seeks special treatment for groups of people, regardless of the mental, physical, or moral capacity of each member of a group. (It’s just a variant of white supremacy.)

Which brings me to the deeper reason why conservatives and (some) libertarians instinctively cringe and react negatively to political correctness. Conservatives and libertarians are big on personal responsibility. It’s at the center of libertarianism. It plays an important role in conservatism, where personal responsibility includes not only responsibility for one’s self and for one’s role in society (properly understood), but also responsibility for the observance and continuance of time-tested social norms.

Political correctness casts personal responsibility aside and replaces it with identity politics. That’s the deeper reason why conservatives and (some) libertarians cringe and react negatively to it.

UPDATE 12/09/16

Travis Scott focuses on one (of many) counterproductive effects of political correctness in “The Science Says Putting Women into Combat Endangers National Security” (The Federalist, December 9, 2016). Title of the article speaks for itself. I will quote two passages. The first is about the apprehension of an intruder who climbed over a fence at the White House:

In 2014, a veteran named Omar Gonzalez jumped a fence and rushed the White House. He had a weapon, and made it all the way across the green lawn and into the White House. He was first confronted in the White House by a lone guard, whom he overpowered with ease. He ran through the White House and was not apprehended until he got to the East Room.

Many of the news reports failed to mention that the guard Gonzalez overpowered was a female member of the Secret Service, and that the people who apprehended Gonzalez were males. While the president’s life may have been put in jeopardy by putting a female guard between him and a knife-wielding wild man (a guard the Secret Service had deemed physically fit enough to defend the president), other issues were addressed instead, such as “added layers” of security to the lawn of the White House.

That’s just a single illustration of the folly of the politically correct position which says that women can do everything that men can do. (Most men — conservatives ones, at least — wouldn’t think of claiming that they can do everything that women can do.) More generally, with respect to gender integration of combat forces, Scott writes about the Marine Corps study:

Coinciding with all previous research and scientific findings, in military training also women fail at incredibly higher rates at physically demanding tasks. In 2015, the Marine Corps concluded a yearlong study of how de-sexing units would affect combat readiness. They found: “all-male units were faster, more lethal and able to evacuate casualties in less time… All-male squads, the study found, performed better than mixed gender units across the board. The males were more accurate hitting targets, faster at climbing over obstacles, better at avoiding injuries.” Similar studies within our military, and even from other countries, reinforce these findings.

Irrationally, government officials in the Obama administration have opted to ignore all available scientific data to forward their own politically correct agenda. This suggests they didn’t care what the science said to begin with. It means they are willing to degrade the quality of the military’s effectiveness to artificially advance women who can’t compete by the same standards, and by doing this they are knowingly putting our soldiers at greater risk for injury and death. For this, their actions are condemnable before God and all the men of their country.

While some nitpick the all-male versus mixed-sex units study, no one has suggested studying how effective all-male units would be against all-female units. Not only are there simply not enough women capable and willing to fill such roles, but nobody thinks all-female units could be as effective as all-male units. It should stand to reason that because we know women are weaker then men on a biological level, that it should be obvious that integrating women into all-male units would tactically weaken those units. When you take these plain truths and put them together, the Marine Corps findings aren’t all that surprising.

Sgt. Maj. Justin D. Lehew, who was a part of this Marine Corps study, lashed back at critics who claimed “better women could have been picked,” and that the evaluators’ mindsets were “biased” against women from the start:

We selected our best women for this test unit, selected our most mature female leaders as well. The men (me included) were the most progressive and open minded that you could get… The best women in The GCEITF as a group in regard to infantry operations were equal or below in most all cases to the lowest 5 percent of men as a group in this test study. They are slower on all accounts in almost every technical and tactical aspect and physically weaker in every aspect across the range of military operations… Listen up folks. Your senior leadership of this country does not want to see America overwhelmingly succeed on the battlefield, it wants to ensure that everyone has an opportunity to pursue whatever they want regardless of the outcome on national security…There is nothing gender biased about this, it is what it is. You will never see a female Quarterback in the NFL, there will never be a female center on any NHL team and you will never see a female batting in the number 4 spot for the New York Yankees. It is what it is.

What it comes down to is this: Conservatives are realists. Politically correct “liberals” are fantasists.
