First you have to acknowledge the greater context: The vast majority of kids & teens with gender dysphoria desist, naturally. Most of those who desist are gay & lesbian. Among the ones who don't desist, a high proportion of them are exclusively same-sex attracted. There has been a recent trend of straight girls transition that never used to exist. The demographic least likely to experience gender dysphoria has quickly become the most likely to experience gender dysphoria.

So instead of the question being: what do we do with people who have gender dysphoria, the real question is why do some people with gender dysphoria fail to desist? Desistance is totally natural & cures dysphoria, while transition doesn't. So why not encourage desistance, instead of transition?

Also, knowing the greater context, if you come across a girl who says she has gender dysphoria & wants to be a boy, what situation would transition actually make sense? If she is a lesbian, you know that she is likely just going through a phase that predominantly affects homosexuals. If she is straight, you know she is likely just a victim of a modern trend; a social contagion. So in neither case would it make sense to medically transition her.

The term 'gender dysphoria' makes no sense. If it's dysphoria (the opposite of euphoria, a type of depression) then it is a mental disorder. If gender is not sex, but the social constructs of masculinity & femininity, then the "disorder" would be limited to clothing, behaviours, pronouns, not their sex. So why treat it as it as if there is something wrong with their perfectly healthy body? Why create a hormonal imbalance where none previously existed? Why amputate healthy body parts? Why not treat a mental disorder like a mental disorder? It clearly should have been called 'sex dysmorphia', or something like that, but even then, the cure to dysmorphia is not cosmetic surgery or chemical castration.

The medical industry is treating "gender dysphoric" children the way they used to treat children with DSDs. Sex reassignment surgery was wrong in the case of intersex people & no less wrong in the case of people with a cross-gender identification.

Social transition often leads to medical transition, & legal transition, so it doesn't stop at pronoun usage, typically. I would advise against it.
