Thanks for such a thoughtful and detailed response, Spooky - really appreciate it.
I think Clymene has it, though. I
All of the examples you provide where "in some situations it’s not and a more precise phrasing is needed" are the direct consequence of a movement that insists that transpeople are described as belonging to a different sex class to that to which they actually belong.
In other words, that quote itself - "in some situations it’s not and a more precise phrasing is needed" - is evidence of the damage being done to women here. We didn't need more precise phrasing in the past: who and what we are has been changed and confused, and the language used to communicate to us, including other vulnerable groups needing clear language, has been changed and confused.
Why must the language used to describe us be changed? The additive approach of using "women and transmen" (with "transwomen" accepting the differences between the class of "women" and that of "transwomen", proudly retaining their own name, and therefore not finding anything offensive in that) would ensure clarity for transpeople while retaining it for women. Instead, we're being asked to sacrifice the only word we had by which we understood ourselves.
Even your acknowledgement "yes I would agree that that would also be offensive" stands in interesting contrast to your concerns about misgendering. Why is one group's perception of offence unquestioningly validated, while ours is carefully gauged as reasonable or not?
You say "no one is saying" and use the word "must" to suggest I can still use "woman" as I wish - yes, I can use the word, but no, I can't use the word in the way in which I want, with the meaning I previously understood. I went on to the NHS website recently, and there it was, "people who menstruate". This does effectively function as an implicit requirement that I accept my own redefinition, because it's a clear indication that the NHS believes woman refers to gender identity. In that context, any NHS box I subsequently tick to identify myself as a woman becomes almost coercive - it is demanding that I say that I accept this new definition, agree to my own inclusion within it, or suffer the consequences (no treatment, accusations of transphobia etc.)
These may seem like small, semantic issues, but they're not. They're the thing end of a wedge that ends with Isla Bryson. My sense that I should defend my strength of feeling is, in itself, telling evidence of the double standards at play here. Put simply, we have two groups who wish to have the right to define themselves, one to protect themselves against very genuine and desperate psychological distress, and the other to maximise the clarity that enables them full representation and participation in society (and because of a not inconsiderable degree of distress themselves). One of these groups is being dismissed and subsumed into the interests of the other without debate, and with attempts to debate being actively shut down as unconscionable.
This, to me, is evidence of deep-seated misogyny. I can find no other explanation.
