Because I have no reason to believe biological gender exists separate from biological sex. No one can point to it nor create a test for it.
edit: It seems to me that it costs a person almost nothing to believe somebody about their subjective belief of their gender, yet it seems that a lot of people resist so strongly. Why is this?
My objections on the topic are fairly simple:
* We shouldn't create laws around activities or identities that cannot be objectively measured.
* Peoples personally held identities shouldn't be foisted up such that everyone must accept them unquestionably.
People should be free to love, fuck, marry whomever they want and express themselves in whatever degree of masculinity or femininity they are comfortable with. If we had widely known gender-neutral pronouns, I would use them.
This is a big problem with the growing predominance of "virtue signaling" in such discussions. Few people actually want to read/listen and understand someone's point of view before jumping on them for having the "wrong opinion."
We do develop standards for manslaughter versus murder 1, but my understanding is that the accused killer's mindset (their "intent") is an important distinction.
Most traits associated with sex are not universally determined by sex. One example in humans is males that have XX chromosomes[0]. For another example see AIS[1].
We observe more than two genders expressed in non-human animals:
>Side-blotched lizards are notable for having the highest number of distinct male and female morphs or "genders" within a species: three male and two female. [2]
It is extremely unlikely that given the diversity of phenotype expression we see in life there would be no cases in which sex does not match gender. A claim that sex and gender match perfectly in all cases requires enormous evidentary support as it contradicts much of current science and biology.
>No one can point to it nor create a test for it.
You can ask someone, that is generally how we determine how much pain someone is in.

I have no objection to the degree that someone wants to express themselves with stereotypical masculine or feminine traits. Elevating cultural stereotypes to the level of phenotype is not supported by anything you've linked to, though.

This is true, but we don't create laws around someone's reported degree of pain. Doctors are also given then discretion to deny someone pain medication if they believe the patient is lying in order to get high (though I disagree with this on grounds of drug decriminalization).
