@bd67thSaysReinstateLangCleg I think in the UK the "Jane, formerly John, doesn't need it" argument would not apply. As far as I understand the legislation (IANAL), an issue doesn't need to affect only women for a situation to count as sex discrimination, it only needs to affect women as a group disproportionately.
For instance, the equal pay claim I had to fight a few years back. It was a big firm I worked for (and a cock-up rather than conspiracy situation - average pay had drifted apart at each grade due to long pay scales and automatic "average" markings if you were on maternity leave, coupled with long pay scales). It was not that there was no man with my length of service at my pay grade paid less than me - there were. It was that there weree disproportionately more men with similar length of service at my pay grade paid more than I and a group of my female colleagues - because we had had maternity leave(s) and they had not.
Same would apply to Jane-formerly-John not needing size D work boots. So long as women on average needed them and men did not, equality provisions would apply.
Ditto free san pro, free prescribable contraception...
As I've said before, most of the time the legal fiction that transwomen are to be treated as women (in most, but not all circs) doesn't cause problem for women.
It very much does cause women problems in sport, women's prisons, women's single sex accommodation (shared dorms, refuges, two-woman hall of residence bedrooms), women's right to a HCP of the same sex for intimate exams.
Philosophically I am very much TWAM. However, pragmatically in terms of what we're likely to be successful campaigning for, I think the important issue is protecting (and strengthening) legislation to allow us to retain women's sport segregated by sex, women's prisons segregated by sex, women's single sex accommodation (shared dorms, refuges, two-woman hall of residence bedrooms), women's right to a HCP of the same sex for intimate exams.
We need to keep banging the drum for sex as a protected characteristic in its own right, distinct from gender. I look upon protecting "gender" as a bit like protecting "freedom of religious belief" - we should, as a civilised society, allow people to believe all sorts of batshit things without discriminating against them because they believe batshit things.
For instance, I've known several very good physical scientists who (because of their religious beliefs) were young-Earth creationists (
). I'd hate to see them discriminated against in employment because of this so long as it wasn't actually preventing them doing their job properly (they were, as I say, physical scientists - I don't think it would be appropriate for a young Earth creationist to teach biology in school).
