You keep repeating yourself because you keep revisiting your basic premise and spelling out your argument. I do that, too, usually in the Israel/Palestine threads when people ignore history and facts. The difference I see happening here is that there are two separate things, sex and gender, under discussion. Posters here accept the facts you present about sex and sexual development, but you don't appear to accept facts about identity and gender.
Actually, there are several posters here who reject the facts I've presented about sex and sexual development. A whole lot of them persist in misrepresenting how sex is defined. Thus I keep repeating it. Specifically, sex is not defined by karyotype, but by reproductive phenotype. That's what allows it to be a universal definition of male and female across all anisogamous species including a large number of plants.
Yes, there are two sexes in humans, male and female.
Happy to have you join us in the binary sex cohort.
Every time I look into who is ardently advocating for "intersex" being recognized as a valid category, I find people like
Dana Zzyym, who fought for years to have the reality of their intersex status recognized and respected so that kids born with intersex conditions don't have to endure the pain and suffering they did when doctors try to "fix" them.
Yep. You might note that Zzyym bases almost every discussion they engage in on their identity not their condition. I can't even find any mention of what DSD Zzyym has. All of their activism is based around them being "nonbinary", not at all around medical support and treatment for their medical condition.
On the other hand... if you research disorders of sexual development, you'll find support groups and medical discussions about treatment. And you'll find a lot of reproductive biologists presenting research on the fetal development process, the mechanism for each of those different conditions, how they present, what long term risks and impacts they have... as well as advocacy for not performing infant surgeries unless there's a functional problem that needs to be addressed. And you'll find people with actual DSDs who are pretty pissed off about their medical conditions being appropriated by an ideological movement.
It's really a very different perspective.
"Intersex" is a term that describes people who don't meet all the criteria for one of the two sex categories, or who have physical characteristics of both. It is the catch-all term for the end result of a lot of different developmental pathways that lead to one having ambiguous genitalia or sex organs of more than one sex. It doesn't have to be precisely defined for it to be an accurate, useful, and valid designation.
It was a term that was used for a while - and it turns out that the people who have those conditions largely objected to it specifically because it gives the false impression that they're some other sex. These days, it's used almost exclusively by transgender activists - and it's used to falsely support the "sex is a spectrum" narrative. That "sex is a spectrum" narrative is then used to support the notion that it's possible for someone to have an entirely normal karyotype and phenotype, but somehow be "really" the opposite sex because of their beliefs about themselves. Thus a male who has an entirely normal male body, an entirely normal male reproductive system, and an entirely normal male development during puberty can declare themselves to be "a woman" on the basis of their feelings, and then make the fallacious argument that they have a "woman mind" and therefore should be allowed to strip down in the women's side of the nude spa and show off their ladydick.
Very genuinely - people who actually have disorders of sexual development very strongly prefer NOT to be referred to as "intersex".
Aside from that, the criteria for each sex category is pretty straightforward 99.98% of time at birth, and 99.999% of the time at puberty. The criteria is did this person's fetal development follow a mullerian or a wolffian path? Even if their development was incomplete, we can ultimately identify a person's sex via a test for the presence of the SRY gene and the ability to receive testosterone. If both of those are present, the individual is a male of the human species. That's the mechanism for sex differentiation in utero.
Even if we only recognize two sexes and sort everyone into one or the other, that does not mean there are only two genders, or that gender is immutable.
Gender identity can be whatever the heck you want it to be. It's irrelevant to me, and if it makes someone else happy no problem.
I'm concerned about policies in those few instances where sex actually matters: intimate spaces, sex-specific services, prisons, and sports.
