Once your eyes return to their normal operating positions, would you like to address the points I raised here:

Since that post was left behind in the thread continuation, I'll repost it here for your convenience:
The whole thing is a sidetrack, really. I'm not here to engage your Devil's advocacy on the ease of observing someone's sex, or the relative significance of edge cases not actually relevant to the questions I have.
The questions I have being these:
1. To what degree should transwomen be entitled to access sex-segregated spaces for women?
2. On on what basis, if any, should such access be granted?
At the start of this thread, the space I mainly had in mind was women's restrooms, and I didn't really think of it as "sex-segregated". My answers to my two questions would have been:
1. "Total access [to women's restrooms]."
2. "On the basis of self-ID, however I would like to know how we can enable self-ID without allowing predatory males to exploit it, and without having to implement some sort official paperwork ID instead."
Nowadays, my thinking about all that has changed quite a bit, for reasons belabored at length and in depth in this thread. And I still haven't seen even any kind of attempt at addressing my concern in question 2.
If you have answers or arguments relating to those two questions, I'm happy to continue our conversation along those lines. Especially if you have an answer for my concern in question 2.
Otherwise, if you're still on the fence and inclined to more Devil's advocacy, try this one from the other side of the fence: The stipulated position is that fiat self-ID should be the basis for trans access to sex-segregated spaces, and that any kind of "papers please" solution is right out. I'd be interested in seeing your counter-argument to that position, playing the Devil's advocate.
ETA: I'd also very much like to see your reasoning for your claim that it is easier to determine someone's date of birth than their sex.
