Vestal
Added to this biological differences can lead to differences in behaviour, the link between different levels of testosterone and aggression for example.
That is sex, not gender. Which is why I don't want males in women's spaces regardless of the "gender" as which those males identify.
It is not, when these different hormone levels, do not make violence pre-requisite. It indicates predisposition not causality. Gene expression, for example, can vary due to environment, brain physiology due to prolonged thought patterns.
Gender, on the other hand, is telling people what they ought to do, either because of their actual sex, or, nowadays, because of their actual sex AND because they have failed to identify as the other sex. We do not need that. We do not need to make it more inclusive, we can just do away with it.
If gender was fully inclusive, people would be told the characteristic behaviours and presentation of their sex are equal to and as diverse as those of the opposite sex. They would be told there is no requirement for any distinct gender differences between the sexes.
That - socializing boys to be aggressive and entitled - is gender. Why would anyone want to keep that?
Indeed, that is not what I am proposing, at all. I would propose both sexes are encouraged to be assertive when appropriate, instead.
