Welcome to the thread! I know you've been here before, but let me take this opportunity to welcome you.
Thanks.
Thanks for the references and citations. They seem to parallel my own thinking, and reach similar conclusions, as do you yourself.
Share the wealth, praise the lord and pass the ammunition.

Complex issue, maybe more complex than it maybe needs to be. But some clarification seems urgently required to resolve the issue.
You should probably note that I've been in this thread, discussing these issues, for several years. A lot of the reasoning you're presenting here is already familiar to me. I'm glad to see we're in agreement on at least some of the points raised.
Consensus is a good thing, generally speaking in any case.

United we stand, divided we fall and all that.
Finally, I've been around and around on this topic for quite a while now, as I said. For me, at this point, I consider almost all the questions either already answered, or else largely irrelevant. My one remaining area of interest and focus is recommendations for public policy, and the reasoning behind them. Should transwomen be housed in women's prisons? Should they have the right to compete in women's sports? Those kinds of policy questions.
I'll probably have to at least skim through some of the last 45 pages on the topic to get a "lay of the land", but to answer your questions - offhand, shooting from the hip - I'd say that the topic question or thesis - "transwomen are not women" - seems to be something of a red herring. Not sure if the question has been explicitly stated this baldly, but your questions seem to boil down into whether penis-havers should be housed in women's prisons, whether XYers should have a right to compete in sports leagues historically reserved for XXers. Think the answers should be obvious in that case.
As I put it in the DSD thread:
You need to ask yourself, what exactly are our objectives? Clearly, it's to give some measure of privacy and safety for vagina-havers by excluding penis-havers from those venues [toilets, change-rooms, sports leagues]. Reproductive abilities - past, present, or future - generally have diddly-squat to do that objective. Much of the "debate" over the biological definitions for the sexes is something of red herring, and serves only to muddy the waters, corrupt the biological definitions, and give free rein to the transloonie nutcases.

Questions about gender, about sex as a binary or a spectrum, and about "what is a woman" generally serve only to obscure those nitty-gritty realities. They have largely served only to create something of a Gordian Knot of mythic proportions - which I think you may have alluded to at one point.
Somewhat apropos of which, you might enjoy a post over on Colin Wright's Substack on the biological definitions of the sexes by philosopher Tomas Bogardus:

Bonus is a comment over there by yours truly critiquing his "arguments" ...
But somewhat more importantly is this oldish essay by Bogardus on
Evaluating Arguments for the Sex/Gender Distinction:

Been a couple years since I read it and I'll have to take a bit more time to pick up the threads, but, offhand I'd say he's contributing mightily to the creation of that Gordian Knot with a bunch of largely impenetrable bafflegab and self-serving claptrap, both his own and that of others. And his Substack is little better for peddling a rather egregiously unscientific definition for the sexes.
Seems to me that the only reasonable way of cutting through that Gordian Knot is to be clear on what our objectives are. And be willing to call a spade an effen shovel, to define our terms clearly and objectively with no fear or favour.
In the DSD thread, you've repeatedly suggested that our current definition of sex has important implications for public policy decisions regarding trans people. Can you give us some details about what you mean?
Good question, one not easily answered in a dozen words or so. As I've suggested above, I think that the fractious "debate" over achieving coherent definitions for both sex and gender tends to preclude answering the questions you raised above. The objectives I've suggested seem paramount, should be our focus, although I suppose "gender dysphoria" is part and parcel of that.
But the path to those objectives seems badly littered with any number of pitfalls created by those debates, by a lack of consensus over what we mean by sex and gender - Bogardus' old essay being a case in point. Going to be a challenge to achieve that consensus, but seems to be Job One.
