The Gender Agenda is Alive in “Science,” By Mrs. Vera West

Maggie Ruderman and Kimberly Zayhowski, "Why Genetic Testing Can't Always Reveal the Sex of a Baby," discuss some of the limitations of genetic tests during pregnancy to determine the sex of a baby, as other factors work with the sex chromosomes to determine sex: https://www.livescience.com/health/genetics/why-genetic-testing-cant-always-reveal-the-sex-of-a-baby?utm_source=pushly&utm_campaign=MANUAL

That is fine, but then they spend most of the article advancing the now well-known case for the non-binary view, that the categories of male and female are not exhaustive. There are intersex people, for example:

"Intersex people, or those with variations in sex characteristics that deviate from societal norms of binary sex, exemplify the complexities of sex. These variations can manifest in various ways beyond X and Y chromosomes, such as differences in hormone levels, genitalia or secondary sexual characteristics.

The oversimplification of sex based on societal norms has led many to believe that there are only two discrete sexes. The binary framework of sex excludes intersex people and perpetuates their erasure and mistreatment within both health care and society at large.

For instance, many intersex individuals face unnecessary surgeries, such as nonconsensual genital procedures."

Then there is the gender issue, that of psycho-social identification, and there almost anything goes:

"Gender is not dependent on anatomical parts or chromosomes. People are not math equations, and having certain combinations of biological parts does not equal someone's gender. For example, some people may be transgender, meaning their assigned sex is not congruent with their socially or self-defined gender. Nonbinary people do not identify exclusively with either of the two genders in the binary, regardless of their assigned sex.

Just like sex diversity, gender diversity is not rare. A 2022 Pew Research Center analysis found that approximately 5% of adults in the U.S. under the age of 30 are transgender or nonbinary.

These estimates will likely increase as societal awareness and acceptance of gender-diverse individuals increases. Anti-transgender legislation often oversimplifies gender as strictly binary, conflating it solely with sex assigned at birth.

Intersex and gender-diverse people show that sex and gender are both multidimensional. Gender is not solely determined by biology, and it is erroneous to define someone's gender by their sex, much less by their sex chromosomes."

Naturally, this leads to a socialist view of sex/gender, something Engels would be happy with:

"The idea that biology plays the largest role in determining who an individual is, or bioessentialism, has governed misconceptions about sex and gender for many years. This concept is used to confine people to buckets and limit their self-determination.

For instance, societal norms dictate that women should be nurturing and gentle, while men are expected to be protective and assertive. Such rigid gender roles, often enforced through the lens of biology, serve to uphold notions of evolutionary destiny and a purported natural order.

Marketing strategies for children's toys often adhere strictly to gender roles, steering girls toward dolls and domestic play sets while steering boys toward action figures and construction sets.

Educational systems often reinforce gender norms by directing girls toward subjects such as literature and arts while steering boys toward science and mathematics. This perpetuates the notion that certain traits and interests are inherently linked to one's sex and gender, thereby reinforcing societal norms and sustaining inequality.

Upholding binary constructs of sex and gender does not allow for individuality and gender fluidity. Categorizing people from the time their chromosomes are analyzed or the moment their genitals are observed at birth restricts their autonomy and authenticity. These simple assumptions set expectations that can be harmful."

To deconstruct all this, note that the existence of intersex people does not invalidate the binary distinction between males and females. The intersex have mixed characteristics, but these characteristics are defined in the first place using binary conceptions. As I often say, the distinction between plants and animals is not invalidated because of the existence of organisms having characteristics of both. The world is vague, and all things are fuzzy; there is no sharp dividing line between the colours red and orange, yet these distinct colours exist. Thus, the main argument getting the whole thing going here collapses.

Their line taken is that it is culture, rather than biology which determines sex and gender; but this position is subject to heavy critique which I have reported on previously at the blog. Yet, we do not hear any opposing evidence in the article.
