When I say sex lies deeper, I mean it is defined separately to one's appearance (e.g. hair length, genitals, a particular chromosome or not), in terms of one’s sex itself. — TheWillowOfDarkness
I understand what you are saying, but I can not agree with it.
Chromosomes (which are groupings of DNA) are the basis of sex (as far as I know). The sex-linked chromosomes determine sex. What determines sex
uality (gay, straight, fetishist, celibate, whatever) is another kettle of fish. Certain aspects of appearance (certainly NOT hair length) are determined by the chromosomes: ovaries/uterus or testes/penis, and numerous other sex-linked characteristics.
I don't know where the basis of sex could lie, deeper or not, if it was not in the DNA groupings of chromosomes. For all but a small fraction of people (far less than 1%) the XX and XY chromosomes agree with the person's self-conception of their sex (separate from sex
uality). "Medical authority figures in the United States most often quote a prevalence of 1 in 30,000 for MtF transsexualism and 1 in 100,000 for FtM transsexualism." (University of Michigan)
That a small number of people's chromosomes do not match their perceived sex does not negate the principles of how sex is determined physically.
When I say sex lies deeper, I mean it is defined separately to one's appearance (e.g. hair length, genitals, a particular chromosome or not), in terms of one’s sex itself. It is not a status obtained by having one sort of appearance or another, but a substantial feature itself. — TheWillowOfDarkness
If that works for you, fine. To me it sounds non-sensical. In my experience, men who look like men (general physical characteristics, specifics of penis, testicles, beard, body hair, manner-of-being-in-the-world) also act and identify as men. The same (different features) goes for women. Not 100% of the time, but more than 99%. Maybe I hang around with an unusually conventional group of people, but I don't think that is the case.
It IS the case that men and women can perform many roles traditionally assigned to the opposite. Men can be effective nurses, women can be effective soldiers (so reports have it, anyway). Some men are homebodies, and some women are out carousing all night. But female soldiers and all-night carousers generally think of themselves as women. Male nurses and homebodies continue to them of themselves as men.
Were society organized differently (in other cultures it has been) men and women occupy roles which in the US are oppositely assigned. For instance, women in many countries do heavy outdoor work, not exclusively, but consistently.
It is my impression that you are NOT talking about gender-linked occupational roles -- like only men get to be bricklayers and only women get to be nurses.
