The awfulness of feminism was not always obvious. The “first wave” of feminism, conveniently called first-wave feminism, was about women getting the vote and some legal protections. A lot of men knew giving women the vote was a bad idea, but not so bad that they were willing to fight to stop it. A century ago when women were demanding the vote, feminism did not look like an assault on nature. It was just unattractive women making a nuisance of themselves in public.

Second-wave feminism is where the nuttiness bobbed above the water line. That’s where we get words like “gender” worming their way into our vocabulary. That is, sex is an arbitrary construct created by men to oppress women. The remedy was to smash up family life, give women a handful of rubbers and money for cab fare as dating aids and demand that men stop thinking about sex. That sounds crude, but crudeness was the most obvious feature of second wave feminism in the 60’s and 70’s.

Third-wave feminism takes this to another level of crazy where reality is infinitely negotiable. Here we get a variety of new sexes, claims about women being witches from another planet and the sun revolves around the earth. That sounds like mockery, but it is hard to satire this stuff. When people are claiming the biology is not just a social construct, but part of a grand conspiracy, it’s hard to not mock it. Despite this, the lunacy has just started. Soon, men will be afraid to around women in the office or even in public.

Crazy rants against nature in the abstract are one thing. Sitting in your college office ranting about males has a different result than throwing yourself off the roof claiming you can fly. But, the crazy rants eventually lead to someone testing the theory. The insanity of feminism is now showing up in the emergency rooms of America as women and girls test the theory that there is no biological difference between men and women. At the Olympics, girls competing on courses built for men are getting hurt a lot.

Sarka Pancochova, a Czech snowboarder, led the slopestyle event after the first run. On her second trip down the course of obstacles and jumps, she flew through the air, performed a high-arcing, spinning trick and smacked her head upon landing. Her limp body spun like a propeller into the gully between jumps and slid to a stop.

Pancochova was soon on her feet, and the uneasy crowd cheered. Her helmet was cracked nearly in half, back to front.

She was one of the lucky ones, seemingly O.K., but her crash last week was indicative of a bigger issue: a messy collage of violent wipeouts at these Olympics. Most of the accidents have occurred at the Rosa Khutor Extreme Park, the site of the snowboarding and freestyle skiing events like halfpipe, slopestyle and moguls.

And most of the injuries have been sustained by women.

The rants against nature are not just showing up in silly snow activities. The US military is putting women in combat units. It is one thing for a gal to break her neck trying to ski like a boy. It is unfortunate and sad, but not the end of the world for anyone but her. Putting physically and mentally inferior soldiers into combat units is another matter. That’s where mother nature let’s you know reality is not negotiable. Men in combat have a way to handle the physically and mentally unfit within their ranks.

Women are not men. Men are bigger, faster and stronger than women. Studies have been conducted using the mountain of data collected by the military over the last 100 years. One of the ancillary benefits of having a massive standing army is a massive amount of data about the humans entering and serving in that standing army. It provides the best cross-section of the American population possible. Since America is a mixed society, it works as a handy proxy for the human race in general.

“Using the standard Army Physical Fitness Test … the upper quintile of women at West Point achieved scores on the test equivalent to the bottom quintile of men.”

West Point is a training center for the very best who are willing to join the Army. What the data shows is the best women are physically the same as the very worst men. That may not sound so bad, but according to the data, “the average 20-to-30 year-old woman has the same aerobic capacity as a 50 year-old man.” Anyone who has played sports, goes to the gym or lived on earth knows this is fairly obvious. There is a reason why girls don’t play football and boys are not allowed to play in women’s sports.

There’s another bit to this. Women and men think differently too. For instance, there are differences in IQ. Males are over represented in fields like math and science, but under represented in nurturing professions like education and medicine. The difference between men and women show up across the range of human attributes. Men and women are different and they are complimentary. For all of human history, people, both sexes, understood and excepted this.
