> Why would you conclude that it is impossibility that someone's biological sex may not be the same as biological gender? 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.
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.
