"I can't interact with you unless I know what your genitals look like"

But it's discrimination to make fat people pay nore for a ticket.

...no, I really want to know...

Because virgins aren't allowed in, duh

Mostly so they can more easily punish those who dare to stray too far from stereotypical gender roles.

Different societies consider it an important part of one's identify.

Some countries have religion on the passport.

¯\_(ツ)_/¯l

It does seem a bit weird. Who would I have to screw to board the plane? The pilot?

If they couldn't attack blacks, Jews, women, gays, trans, and now liberals, then they'd actually have to do some work.

I mean the US government is literally shutdown but they still have time for this bullshit....

It was, already. That's why some documents have "X" in the first place. The government is explicitly directing them to ignore that, and just make shit up to put in that field.

I’m also old, and often confused, but less about this one, because of personal experience.

The world is shifting quickly away from “almost everyone adheres to gender norms” to “what’s wrong with people being perceived the way they’d like to be?”

It’s about individual expression of self. The bits and bobs that people have under their clothes may have zero correlation with what their traditionally recognized appearance is.

If someone is lost or a threat, it makes more sense to look for them based on how they present themselves in public, and not how they look naked. (Which can be ambiguous, too.)

Your recognizing your own confusion is a good thing. It means that you are aware that there are still things you need to learn. You’re all right.

If they're putting out a description, someone with an X market is probably better visually described as "gender non-conforming" than a gender they're not really presenting as. They may even present as one gender for the flight and then another when out in public, so being described with one gender could actively disrupt visual identification.

I mean at that point it's just philosophical. Is a woman an ideal for you to fit, or is it defined what the people do, how they act, and what they wear?

Is that a bomb in your pants? Security has no idea as most airport breech tests fail.
