A useful explainer for bewildered relatives, etc.:

Clear definitions of categories matter in the law. The use of two sex categories to talk about a species is standard in biology. In many animal species, including people, however, there are individuals who are neither male nor female or who are sometimes both. In other species, there are two sexes, but they aren’t male and female (usually these are intersex and male). And a few species have only one sex (usually female). The biological reality is that “male” and “female” are not universal immutable biological classifications but rather descriptions of typical patterns in reproductive biology. These categories, male and female, are used by biologists who fully understand that they rarely represent all the relevant biological variation in any given species or identical sets of variation across different species.

Sex is not one single, simple, uniform biological reality. Thus, biology cannot be invoked as a basis for such in legal terms. That’s the bottom line.

Of course, men and women are not the same, and reproductive biology does structure important aspects of human bodies and lives. But none of the key biological systems associated with sex in humans (chromosomes, gonads, genetics, hormones, and so on) come exclusively in two “immutable” categories. Yes, most humans have either XX or XY chromosomes, but as Judge Reyes noted, some don’t. People with either testes or ovaries are most common, but some people have both, and a few have ovotestes. Usually those with testes can produce sperm, and those with ovaries produce ova—but not always. The chromosomes one has do not always predict one’s gonads or one’s genitals or even all the elements of one’s reproductive tract. It is true that most people have the “typical” combo of chromosomes, gonad and genitals, yet there are tens of millions of people alive right now who don’t. These people are not errors, aberrations or problems; they are a part of the range of variation in our species. They are all real people. In fact, many who have these variations don’t even know it. You might be one of them.

In making laws, then, we need to recognize what the actual range of variation in sex-related biology is and how it maps across everyone.

A multibillion-dollar slate of moderate climate-mitigation measures in the Biden administration’s Inflation Reduction Act has been met so far with general public approval. But a broader reaction to the historic federal action underlies the discourse: What took you so long?

A survey-based study published on Tuesday suggests that a shared delusion among nearly all Americans could contribute to the long delay in significant federal climate policy. Despite polls showing widespread concern about climate change and majority support for policies to mitigate it, the new study shows that Americans almost universally underestimate the extent of climate concern among their compatriots. They also underestimate the extent of public support—at the state and national level alike—for policy measures to address the climate emergency.

Distorted beliefs about support for climate policy, and about concerns over climate change in general, are so commonly held among the more than 6,000 American adults in the researchers’ nationally representative sample that the study’s authors call these misperceptions a “false social reality.” Recent polls from the Yale Program on Climate Change Communication show that 66 to 80 percent of people in the U.S. support major climate mitigation policies. But participants in the new study estimated that only between 37 and 43 percent do so. A range of 80 to 90 percent of those polled by the researchers underestimated the U.S. population’s climate concern and support for major climate mitigation policies.

Automobile-first ideals dominate in the U.S. Our countryside is carved up by superhighways connecting bedroom suburbs with sprawling cities, with too many nowherevilles surrounded by parking lots and strip malls and ringed with sound barrier walls—all built to serve the sacred automobile. Atop former towns and neighborhoods, broad avenues are lined with drive-through hamburger stands and banks.

Across the country, the car is the only way to get around and not only in rural places. This reliance spawns an ever more disconnected nation of drivers suffering an epidemic of road rage. As Lancaster University sociologist John Urry wrote, “the car is immensely flexible and wholly coercive,” promising freedom but trapping drivers into inhabiting their cars.

A bracing editorial.

In the 1970s a nation confronted a crisis of traffic deaths, many of them deaths of children. Protesters took to the streets to fight an entrenched culture of drivers who considered roads their domain alone. But this wasn’t the U.S.—it was the Netherlands. In 1975 the rate of traffic deaths there was 20 percent higher than in the U.S., but by the mid-2000s it had fallen to 60 percent lower than in the U.S. How did this happen?

Thanks to Stop de Kindermoord (“Stop Child Murder”), a Dutch grassroots movement, traffic deaths fell and streets were restored for people, not cars. Today the country is a haven for cyclists and pedestrians, with people of all ages commuting via protected bike lanes and walking with little fear of being run over. It’s time the U.S. and other countries followed that example.

It's hard to overstate Hardin’s impact on modern environmentalism. His views are taught across ecology, economics, political science and environmental studies. His essay remains an academic blockbuster, with almost 40,000 citations. It still gets republished in prominent environmental anthologies.

But here are some inconvenient truths: Hardin was a racist, eugenicist, nativist and Islamophobe. He is listed by the Southern Poverty Law Center as a known white nationalist. His writings and political activism helped inspire the anti-immigrant hatred spilling across America today.

And he promoted an idea he called “lifeboat ethics”: since global resources are finite, Hardin believed the rich should throw poor people overboard to keep their boat above water.

To create a just and vibrant climate future, we need to instead cast Hardin and his flawed metaphor overboard.

The project’s star success story was a young man named Kirk Andrew Murphy, who had been caught by his father posing in the kitchen in a long T-shirt saying, “Isn’t my dress pretty?” In a 1974 paper research assistant George Rekers and Lovaas described Kirk at age five as “‘swishing’ around the home and clinic, fully dressed as a woman with a long dress, wig, nail polish, high screechy voice, [and] slovenly seductive eyes.” At home, Kirk’s father exchanged his son’s red tokens for beatings with a belt, with Rekers’s approval. Eventually, Kirk’s brother Mark started hiding the red tokens to save Kirk from the abuse.

After 60 sessions in the lab, Kirk was declared cured of sissy-boy syndrome. The psychologists noted that after the treatment, the little boy was no longer upset when his hair was mussed and was eager to go on camping trips with his father. Rekers eventually published nearly 20 papers on his client’s alleged metamorphosis, becoming one of the world’s leading proponents of conversion therapy in the process.

Then in 2003, at age 38, after a series of unsuccessful relationships with women, Kirk died by suicide. His sister Maris told Anderson Cooper on CNN that his treatment at U.C.L.A. “left Kirk just totally stricken with the belief that he was broken, that he was different from everybody else.”

The American Psychological Association and 61 other health care providers’ organizations signed a letter in 2021 denouncing the validity of rapid-onset gender dysphoria (ROGD) as a clinical diagnosis. And a steadily growing body of scientific evidence demonstrates that it does not reflect transgender adolescents’ experiences and that “social contagion” is not causing more young people to seek gender-affirming care. Still, the concept continues to be used to justify anti-trans legislation across the U.S.

“To even say it’s a hypothesis at this point, based on the paucity of research on this, I think is a real stretch,” says Eli Coleman, former president of the World Professional Association for Transgender Health. Coleman helped create the organization’s most recent standards of care for trans people, which endorse and explain the evidence for forms of gender-affirming care.
