The 'people who don't conform to societal expectations of gender = dangerous for kids we must protect' is such an old chestnut of bigotry. It's been used against gay people, it was used against women during just about every wave of feminist civil action, and now it's being used specifically against transwomen. (Because the zeitgeist largely ignores transmen.)
Transphobes think drag and being trans is the same thing, and the goal is to force closets on transwomen. And it's a shame that the only way their empathy can be activated (because they've otherized trans people into nonpeople) is to show them how legislation like this hurts cisgender nonconforming people like a masculine ciswoman in a bathroom that gets accused of being a man or removal of comedies like Mrs. Doubtfire because the be story is a cisman pretending to be a ciswoman and therefore inappropriate for children.
A good parallel to gender affirming care is in athletics; body building and steroids. In both cases, of gender bending or body enhancing, there are many people who visualize themselves as different from their natural physical person. Both sets of people wish to modify their natural attributes, in favor of a science fiction enhanced illusion, that can only appear with synthetic changes, since do not occur naturally with only wishful thinking.
The main reason athletics; those haters in charge, do not allow chemical and surgical modifications, is adding performance enhancing chemicals and procedures are not healthy and can lead to medical problems and issues down the line. The gender drugs are much newer, than athletic performance enhancing drugs, so the risks are worse for synthetic gender bending care.
There is a lot of personal and peer pressure, in both cases, to perform as one visualizes. Many are willing to take the chance, since if they do not get the synthetic care and others get the opportunity, they will be at a disadvantage. If one state or their entire country bans the drugs, for either scenario, they may need to buy overseas or imports from the black market.
Almost all amateur and professional sports prohibit the use of drugs to enhance performance. I am surprised that the Left is not up in arms protecting the fantasies of the muscle head and athletes from those Right Wing haters. Why do we discriminate against adults in Pro Sports, who only wish to become better, but allow minors to get artificial drugs for sexual alterations so they can become a better them? Does this dual standard make the Left two faced with one hate face, or does their common sense, only come into play when they are detached enough to be objective?
As a compromise, I would allow both the options to get all the synthetic treatment their mental illusions think they need, even though these artificial paths are not organic or green and may cause long term problems. I would even allow steroids to be taken as early as we allow sex altering drugs, so any child can decide if he/she wishes to be a muscle head or a he/she or even both at the same time.
However, those who promote, manufacture, sell and administer these body altering drugs, in both cases, will need to sign a liability agreement, with no statute of limitation. When this goes bad, as it will, heads can roll; civil suits and criminal liability will be enforced. Right now, there is no accountability for those who gain political points and/or profit by subjecting children to treatments that are not long term tested, and are still considered treatments for pathology.
Currently, they will place the burden on the tax payers, half of which do wish any involvement in either body modification care. Maybe the Left can also sign the liability contract, so if there is an attempt to pawn this onto all the tax payers, by crooked lawyers, the Left will bear the full tax liability or help enforce the original liability agreements.
