Politics, not biology, is to drive legal efforts to classify sex
Sex is not a simple biological reality and uniform uniform, so biology cannot be called as a “immutable” basis for legal classification

In the middle of the US legal theater is activated by sex and gender identity Trump Administration Decree “Sex” will be referred to an immutable biological classification of individuals as men or female, “has arrived From a judge.
At once The continued case of military serviceAna Reyes Federal Neighbor Jason Lynch, who defended the commandment of the commandment, asked him: “You understand, as a subject of biology, is that there is only two sexes, right?” And he replied, “I don’t understand to be wrong.” Then the referee illustrated Lynch about the existence of human intersex, who he did not know who had no knowledge. However, Lynch has replaced the US government in a federal court in a “immutable biological classification.
Other clean example comes from February ad, the health and human service departments that extend in the last executive command “Sex-based definitions. “This advertisement reports federal agencies for purposes of completing obligations,” male “is anyone with the reproductive system that creates sperm, and is anyone who creates” female “eggs.

Forensic exchange and HHS edict highlights why and how to discuss too many legal arguments about ideology and non-biology.
Here is the “why” most people, apparently included in HHS, are not known that sexual categories are not understanding of biologists and what is a real biological variation in humans. This lack of knowledge allows idealoga to distort, obtain agendas for exclusion. Decreements are Barbak of cultural war, more than gender issues and transsexual rights, New York Times It has indicated. “How” is about sexual categories in intentional assertions and biologically inaccurate human experiences.
The laws of the category are clear. The use of two sex categories of sexual categories is standard in biology. In many animal species, including people, however, there are men not females or sometimes both. There are two other species in some sex, but they are not men and women (usually those are intersex and men). And some species have only one sex (usually female). The biological reality is that “male” and “females” are not universal biological classifications, but descriptions of typical models in reproductive biology. These categories, men and women, use completely understanding biologists, significantly express them in different species or in equal sets of different species.
Sex is not a simple and uniform biological reality. Thus, biology cannot be based on legal conditions. That’s the bottom line.
Of course, men and women are no The same thing, and reproductive biology structures important aspects of human body and life. But none of the most important biological systems related to human beings “chromosomes, gonads, genetics, etc.) are only two” immutable “categories. Yes, most human beings have XX or XY chromosomesBut as the judge said Reyes, some don’t. People with tests or ovaria are the most common, but some have both, and few ovotestes. Usually those with tests can cause sperm, and those with ovarians produce an oval, but not always. A chromosome does not always anticipate one’s gonads or one’s genitals or one’s own reproductive tract items. It is true that most people have “Typical” combination Chromosomes, gonads and genitals, however, are alive by millions of people right now. These people are not mistakes, aberrations or problems; They are a part of Range of variation in our species. They are all real people. In fact, many of these variations don’t know. May be one of them.
When laws, then, we need to admit the range of variations of biology related to sex and how it is mapped.
Consider Height: Men are the highest percentage of the average of 8 per cent. But most people are no average. If you draw a random set of 50 individuals (25 males and 25 women) and aligned by height, the result would not be all men who were men and women were all. Rather, (usually) the majority of men is half and most central women in the middle. Ignore the average, no everywhere It’s greater than a male person everywhere female person. Not only height. Lately National Health and Nutrition Study Survey data setFifth and 95. Weighed by 75 percent of weight and 95 years, weighed around 110 and 263 pounds of age, and weighed 136 and 287 pounds of age. Therefore, a lot of variation is a mixture of between 136 and 263 pounds, a mixture of women and men. Sex light separation and frequent not often, it extends beyond height and weight, brains, hearts, stomach, bowels, bones, etc.
Yes, there are typical body differences between women and women of the same weight and men, such as the upper body muscle density and some specific hormone levels (but not hormones). How they differ differences, how they were developed, and what they mean, for a particular experience or ability, however, are not any “next to a immutable biological classification”. Distribution of biological human change, military, sports skills, kindergarten, math skills, cuisine love and everything else, is not just a female and male among men “.
This administration is the definition of “sex” deliberately designed citizens to deceive human biology. Any biologist knows this, and Reyes said the judge as a grain of legal concern. From a legal point of view, I think that administratively will be eligible as a reflection of political ideology for any expression. But they have no right to use biology as a “natural” proof of their position “. There are few simple or universal biological biological “rules” that distribute sex categories and humans, but there are important variations and models. Biologists and other scientists understand what biology and lawyness does it and does not tell us that human sex and not us exclude the arguments that are deliberately misunderstood.
Lies should not be despised in our laws. It depends on that life of people.
