In reply to thomasadixon:
> I think it's a bit stronger than that, she's saying that sex = gender. A transwoman has not gone through puberty, has not had periods, has not had the experience of growing/not growing breasts and dealing with the reaction that the changes to their body has in others. Because of that lack of experience, which cannot be gained by anyone not born a woman, they're not a woman. She's saying that being a woman is linked to physical sex in such a way that "feeling" you're a woman can't make you one. IIRC she says that intersex are neither man nor woman (and that there's nothing wrong with that).
If we are to say that the developmental changes and accompanying experiences confer womanhood, then taking hormones can offer something similar- breasts develop, the way of thinking alters, and ( rather like puberty) the resultant changes create an uncertainty in the way the developments are integrated into who you are.
Going further, presumably, a womb transplant could soon be feasible, and with an appropriate regime of hormones you could also have periods which would give something akin to a 'fuller' experience.
Are we then to infer that joining the 'women' category requires that you have to experience the full set of changes ? If so, where does that leave cis- females whose hormonal functioning has arrested, or FGM on pre pubescent girls, or children raised in repressive conditions? Does this sort of thinking add force to the notion that the more male to female gender reassignment surgery you have, the more womanly you'll become? Sure, in chasing extensive surgery, you may be able to 'pass' more easily, yet there are transgender individuals who would say 'I was born in the wrong body' who don't have access to surgery- or perhaps don't even want it.
There are individuals who have had full gender reassignment surgery who view those transgender individuals who have not as second class. But then again, there are cis-females who consider all trans- females as not proper women. But the trans- female might outwardly look more 'womanly' than the cis-female. That trans female might have have only experienced a female puberty as a result of early use of hormone blockers, and been home schooled to shield her from taints of male privilege. The cis-female might have had a very repressed childhood, such that her feelings about puberty were secondary to survival. Which, then is female?
Man is a concept, as is woman, disquieting as that is. Intersex ? "and there's nothing wrong with that"- well, if you were the intersex individual, the chances are that, society as it is, you'd want to identify as male or female, rather than live as an isolated misfit. Intersex may be relevant when it comes to obtaining medical treatment, but outside of that sphere, in an era of supposed equality, perhaps we'd be better just letting them express who they think they are.
I don't think you can tie up all the lose ends in this. A big hairy guy who cross dresses at weekends is probably unlikely to be someone who has a strong and persistent desire to identify as a member of the opposite sex. But for those individuals who do have that overriding sense they were not born in a body appropriate to their feeling of gender, should we say 'no you're not a woman, you're a mentally disturbed man, and the fact that you may have lost your wife, family, house and job is because of your preoccupation with this delusion. It's your responsibility if you suffer harassment and attack, or kill yourself'.
It's as if some sections of society are saying 'We have to put a label on you to make more salient your anomalous existence (but we don't yet have the means to integrate the person with that label into society).'
Until that day, why not just live and let live, eh?
