Keep in mind that a) there's massive amounts of transphobic disinfo around gender affirming care for children, that b) not all trans people have or are aware of their dysphoria, that c) socially transitioning causes huge amounts of euphoria that wear off over time and that d) children still lack a huge part of the physical characteristics that cause dysphoria in the first place. From my personal experience, i'm absolutely not buying that idea, it is the exact opposite of what i experience. Almost everybody i interact with calls me by my real name and genders me correctly, but that doesn't change the fact that living in this skin is slowly, but surely killing me. I don't think i could handle this if i had socially triggered dysphoria on top of the physically triggered dysphoria. This is accutely life-threatenign for me and the idea that actual, pronounced dysphoria doesn't have to be met with gender-affirming care is something i view as actively genocidal against trans people.

It's ofc important not to pathologize transness in itself and to stress there's much, much more to being trans than pain and suffering, that you do not need dysphoria to be valid etc., but downplaying dysphoria in total is simply a threat for trans healthcare.
