I think the term “woman” is, or should be, predicative. Yes, there is a bit of vagueness to “woman” if you want to split hairs. But I think it’s pretty clear that folk-prototypes across a lot of cultures are in close agreement about who women are. The sophistry of genderists thrives in this narrow band of vagueness, but I can’t see how a boy born with a wang and nads who made a career of doing male stuff in the Olympics is going to be able to break through that vagueness barrier and be near the core concept of “woman” just because of what he thinks or what he wants to do.
The whole point is that “trans” is attributive and not predicative in the senses logicians use those terms. X is a trans woman does not simply imply that X is a woman by logical structure. “Trans women are women” is not axiomatic the way some think it is. “Trans” is not a clear subset of “women”, and may not be a subset of women at all. I think it isn’t.
