thirdfiddle your post is absolutely spot on.
I'm in an online group with a bunch of parents who believe that their DC will reveal their gender to them when they're old enough. I was invited by someone a few months back who doesn't know me nearly as well as she thinks she does, who assumed I'd be into this stuff. I stay as it's like a slow moving car crash I find it hard to look away from.
Comments from two mothers of boys stood out to me this week. Both of their sons identify as boys. But both mothers seem to be trying to hold on to the possibility that their DC might be trans or non-binary.
This, for example:
Our oldest is trans non-binary. He most identifies with the term gender creative, in part because he prefers to keep his male name and pronouns for now. He’s 7.5. What we’ve done as a family is talk about all these things openly in a general kind of way, and then check in with him on his own every few months, to make sure he’s feeling good and we are still supporting in the way he needs to be supported.
We have an appointment at the end of this month with a gender clinic, just to find out what our future options might be, and what to look for in terms of puberty if he decides he’d like some kind of intervention like puberty blockers
Why on earth are they talking to a gender clinic?! He isn't showing any signs of identifying as a girl, despite their frequent questioning. This is nuts.
The other mother is asking for advice as her DS clearly IDs as male but has asked his mother to use non-binary pronouns, just at home and not tell anyone. This was after lots of conversations about pronouns from the mother, and he said it was because of his long hair, people think he's a girl. Here's some of the advice given:
Id say as a non-binary person ask. Ask them if they are someone other than a boy or girl and then if offer to look through lists or genders online to see if they can find one that fits. Seems like they are giving clear signals to me. If they were cis would you be questioning outright affirming them?
I think the answer to the last sentence is yes, she would be questioning it if he was "cis" as that's exactly what she and the other parents in the group are doing. Constant questioning of their kids, until they give them the answer they so desperately want to hear - that their kid is extra special and they can now demonstrate how wonderfully accepting they are.
Once the DC have been deemed trans or non binary, do their parents still constantly question them, to check they're not actually "cis"? Do they fuck. Because that'd be "conversion therapy" and what they need is affirmation. 
They honestly can't see what they're doing, is my perception. They really think they're supporting their DC in expressing their true selves, when what they're actually doing is gaslighting them and very damaging.
There are loads of these parents about btw. Not just the small number who hit the press.
Lawyers and therapists are going to make a lot of money out of the fall out from this in years to come.
