We're coming up to the edge of my knowledge of scientific evidence about affirming treatments. I can only refer to pieces written by parents, researchers, and whistleblowers; and logical arguments to support my viewpoint, which is decidedly against the trans movement. Now it's my turn to be ramble on, haha.
My theory is that there is no relief from gender affirming treatments that cannot be better gotten by traditional psychological therapy, self-love, building mental fortitude, and improving family relations. Being in a situation where you're forced to Be A Man (tm) when you really just want to draw is unfortunate, but if that kid enters a clinic and is diagnosed with gender dysphoria rather than as a child of a parent with a potential personality disorder, I think that's a violation of Do No Harm. The former has physical risks that are unrelated to the problem at hand and may even make the child's home life worse.
At the end of the day, my views exist solely to inform my actions. I would be the voice against gender affirming care if it came up with someone I have any responsibility for, regardless of how brutal the backlash to that view would be. Because the risks outweigh the benefits and there are safer, noninvasive, and productive routes that are already well established in psychological treatment.
