Well, the justification for the visa ban is sports, so I could agree that your definition of sex is what matters in this case. But I think in the majority of cases, sex is listed on the passport just to help with identification. If not, then why is it on the passport at all?
There are many definitions of sex. Some would say that sex should be defined chromosomally. I think it would be very unhelpful to put an M on a passport for an XY cis woman -- it should be an F, or maybe an X, if X were just a marker to indicate an unusual edge case. If so, shouldn't transgender people at least be afforded an X on their passport?
And then there's what's between your legs. Well, this is surgically alterable to some extent, so do you mean what's currently between your legs, what appears to be your legs, what was between your legs at birth, etc.? Or do you mean reproductive function? Maybe someone might say that a regular surgery isn't sufficient to change sex, but stem-cell-grown genitals do count as changing sex.
Regarding outward appearance (etc.) being correlated with "sex" (however it's been defined) -- that's exactly my point! In fact, because outward appearance is what is important nearly always -- except possibly in dating, reproduction, and sports -- and because there are a plethora of different meanings when sex is defined as "biological truth," I honestly think that outward appearance (etc.) is what most people actually mean when they say someone is a "man" or a "woman." Therefore, sex, in common usage, is appearance (etc.). This matches with how a tomato is a vegetable culinarily (i.e. colloquially), but a fruit botanically (i.e. "biological truth").
(Anyway, all this is really beside the point of this thread. You can disagree with everything I've said -- I'm just trying to argue that the U.S. is presently a difficult destination for transgender travellers.)
