Why is this even a debatable question?

Washington — The Supreme Court on Thursday allowed the Trump administration to enforce for now its policy ending the use of the "X" marker on passports and requiring the documents to reflect the passport-holder's "biological sex at birth."

The high court agreed to freeze a lower court order that stopped the State Department from enforcing the policy put into place by President Trump earlier this year. The injunction allowed transgender or nonbinary people seeking passports to self-select the sex designation — "M," "F" or "X" — that aligns with their gender identity.

The Supreme Court appeared to split 6-3 in the decision, with the three liberal justices in dissent.

I know a couple whose girl now wants to be a man. I understand, because as a child, she always felt like a boy, and she acted like one too.  
If that's how you want to be, that's fine, and I won't try to forget to call you a he.
She appreciates that I'm trying, because that's what matters most to her.

But she has a female body, although it wasn't visible for a while because she hadn't fully developed yet. Many young children still have to figure out for themselves what gender they are. After all, we're not men or women; we are consciousness, and that's neutral.And that's why children look neutral.

I know the psychology behind this "boy" that makes him want to be a boy.
And I would think it better for "him" if he took on the challenge of facing the pain and his fear he feels for the world outside his super-loving parents, because that's where the root of it lies for him. I am therefore not in favor of continuing this protective climate, especially not when it's advocated by adults struggling with the same challenge.

And when you're a woman who looks and dresses like a man, with a passport you'd rather not have, so what?
You're not a wimp, are you? Where is your spirit?

I do believe we should give children freedom in how they want to express themselves. If you work against that, they'll gravitate more strongly toward the opposite direction.

But I'm not going to pave their adult lives with roses.

I also won't let anyone force me how I have to think, I want to accept you  as best as i can, especially if you're a child, but don't overdo it.
I'm not playing your game.

I knew a grown man who was  a transvestite, and he made a pass at me in women's clothes. Then I'll give you a piece of my mind because I see you're a man, taking on a woman's role because you find it hot, and I don't appreciate that.

If a gay man wants too much attention from me because he can't stay to himself, he'll hear that from me too. I'm not going to tolerate you,

By the way, I do appreciate you discussing things beyond one-liners for once.

And you’re sure don’t seem to have a problem with telling 99.9% of gun owners that they’re are evil and wrong and need to give up their guns. They’re not hurting you. Leave them alone.

Look at the Minneapolis school shooter. The idea that he hid his serious mental issues behind an excuse that he was a woman in a man’s body is preposterous. All of you ridiculous people who buy into this crap need to answer for what he wrote in his diary.

Show me a passport that fires bullets

 Show me a firearm that causes a lifetime of developmental challenge due to permanently altering the chemistry of a child's body.

the REALITY is it's a matter of chromosomes (sp?) or an imbalance there of

 Where did you find this information?

 Chromosomal imbalance is measurable through standard testing.  According to the NIMH the majority of patients indicating gender dysphoria in the past 10 years have standard chromosome features.

 I think Social Media and peer interaction has caused more gender identity change than any amount of chromosomal abnormality.  If what you say is true, the data surrounding chromosomal abnormality impacts would skyrocket.
