Autonomy is threatening

I've been doing some eyerolling about news coverage of Kathy Witterick and David Stocker, the parents who chose not to disclose the geography of their infant's genitalia to the world at large. Starting, and largely ending, with the headlines: "Parents keep child's gender under wraps". They're not keeping their child's gender a secret. They don't know what their child's gender is yet, as the assumption that external genitals precisely determine neurological sex has been empirically proven false. They're doing the loving thing and doing what's best for the child whether or not their child is cissexual or transsexual -- rather than doing what most parents do (albeit because they may not know any better) and doing what's best for an idealized, cissexual version of their child rather than their actual child.

I've also been eyerolling a bit about the internets comments that insist that the child is missing something crucial by not having strangers know whether ze has a penis or a vagina. I mean, seriously? How is an 18-month-old affected by whether others know details about hir genitalia, exactly? By the time the child is old enough to be aware of what it means to be assumed to be a boy, or to be a girl, ze will be able to verbalize whether ze is a boy, a girl, or something else. And at that point, hir parents will respect and affirm hir choice, whether or not it coincides with hir assigned sex at birth -- a privilege that all children should have.

For the rest, I'll quote a comment that was posted on Reddit, since it says what I would say but more succinctly (emphasis original):
Everything about the middle boy's remarks — that is, Jazz's remarks — sounds of his own volition, his own determinism, and his own learning process. What he is learning empirically (indeed, a very early chance at learning what many cis people never do) is that it isn't his articulation of gender that is hegemonic; it's that of the world around him.
He is consciously learning bright and early that you can and will be punished by others for articulating oneself instinctively (i.e., "just being yourself") — just like the lyrics in songs you hear growing up (such as "Free to Be . . . You and Me", which itself even has hegemony unconsciously embedded in the lines "Every boy in this land grows to be his own man / In this land, every girl grows to be her own woman"; we obviously know now that this isn't universally true and never will be universally true; or more accurately, we know that every girl or boy, if making that determination by one's body only, does not universally grow up to be a woman or man, respectively). Just like Andy Samberg emphatically saying that his "dad is not a [cell] phone"," Jazz is learning that pink is not a gender: it is a colour. And he likes that colour on his person. Were this before World War II, no one would have batted an eyelash at him.
And Jazz is also learning that people are programmed by this hegemony that they enforce when they scold him for going with what works well for him, not with what works for them. People know what they're doing when they "police" the articulation of others and how to "police" others, but when you confront them on the question of why — and disallowing the lazy response "This is how it's meant to be" — you witness the breakdown of that hegemonic (il)logic.
Storm, meanwhile, is receiving the novel opportunity that every single trans person I have ever known would have wanted: the agency of self-consent (aka., the elective option to assert a non-elective part of oneself, or choice). That is, trans people have only wanted one thing early on: the autonomy and independent decision making to sort out whether one's neurological sex is on the same side as one's morphological (body) sex — and, by extension, whether the grammatical rules of gender ascribed to people's body morphologies (i.e., feminine for vaginas, masculine for penises) instinctively works for them or not. Those rules of gender exist wholly and independently of both biology and morphology (shape).
Trans people, as a consequence, are punished twice: first, for not being empowered with this autonomy of self-consent; and then punished even harder later for sorting it all out. Social "policing" is always gentle at first (e.g., enforcement through cues of colour and application of when and how to use gendered pronouns) and only gets tougher and more punitive as one's life progresses (e.g., severe beatings at McDonalds, fatal beatings in intimate settings, firings at workplaces, disenfranchisement of citizen rights while still being subject to citizen responsibilities (i.e., discrimination)).
These kids are learning invaluable lessons on life within a social context and putting together the riddle of gender (answer hint: "it's a language"). They are already light years ahead of most adults in understanding this stuff. Wisdom is powerful and, thus, wisdom is going to be threatening and scary to many others who don't understand it.
