Parents have been using their children as social/political projection dumps since time began. The majority of kids will be heavily influenced by whatever ideologies (religious/social/scientific) their parents subscribe to and that will be how it is going forward. As a kid develops into an adult most will break away from the parents and make their own minds up (often starting heavily around teenage years beginning). Which may actually be them subscribing to whatever their parents believe by choice, as in they agree with all their parents have instilled in them. Or when they disagree it often leads to accusations of parents trying to indoctrinate or restrict their learning choice and so on. One of the wonders of the internet is a vast wealth of knowledge for any young teenagers to be able to browse and get some education they may lack from their close minded or overly hostile parents. An area of ongoing improvement though needs to be in schools, as the internet can be far too much of a wild wild west to solely rely on educating minds.
Kids who fail to "grow up" or become adults away from their parents often end up in a therapy of some sorts. It should be no surprise to anyone a lot of issues in adults failing to cope with life ends up coming from parenting, whether a lack of parenting, missing parents or parents who try too hard to get their child(ren) to strictly conform to their views of the world. These sorts of failings usually come from religious indoctrination, but life is complex and there are huge webs of social and political disagreements for people, let alone children/parents to have. While every parent will want to try and somewhat shape or influence their children, there also has to be compassion to love them for who they are and let them make their minds up on many things.
Everyone in here can make calls of what they believe may happen but only time will tell how this kid grows up, and this one decision alone doesn't say everything about how the kid's parents will raise them in totality. It's not new that parents push their views on their kids, it's how it's always been. If it's within the legal system and can't be proven to be abuse, you just have to hope for the best that most parents will do their best to nurture, love and help their child develop without being total dictators about how the child grows and develops.
To be a bit closer related to the whole debate it's no shocker for anyone to admit most children assigned at birth will indeed grow and develop within the route that lines up with their biological appearance (figures are always routinely like 95~99%+). When it becomes clear as a child develops that isn't the case we live in a society where that can be easily changed and supported (at least in some parts of the world). Our best approach is to take a child for what it is and wait until they develop a bit, rather than overly complicate the situation for a baby that cannot even communicate properly. I know it's a heavily contested argument how young is young enough to start making serious changes/discussions, but talking and educating is one thing. It's irreversible biological changes via medication and surgery that are most contested. The short debate being summed up as it's not the case every tomboy girl, or overly sensitive boy is a gender dysphoria case in the making. Hence why kids need to be allowed to be kids sometimes without doctors/psychologists and overly paranoid parents buzzing around them like they're test subjects.
And for what it is worth people who go really far off the deep end and start outright rejecting all biology and psychology, it's not really any worse than people claiming the earth is 6,000 years old or that evolution is a fabrication. Humanity will continue to have many minds that will outright reject evidence and science till humanity is extinct. Or as the anti-vax folk routinely do they take the one report that casts doubt and say "ah hah I knew it" versus the 1,000 that say otherwise. Confirmation bias can be a form of indoctrination for many at times, and in the modern society, there can be a shit ton of bunk published studies.
As for the lowercase name debates, it's nonsensical. It is dumb and nothing on genuine debates around gender/sex, but what can you say, as I said above humanity will continue to do strange things till we go extinct. Structures within our languages, such as capitalisation and punctuation are not forms of oppression though, that much is certain (some posts in here seem to refer to the lawyer somehow suggesting that).
