This "care" is unnecessary and harmful for most children. Puberty is the cure for most children with body dysphoria; up to 90% of kids who identify as transgender desist from this identity post-puberty. However, effects from "gender-affirming care" like a deepened voice, mastectomy, orchiectomy, hysterectomy, and sterilization are irreversible. The long-term effects of puberty blockers especially are unknown, particularly as they affect adolescent brain development. That's without mentioning the usual risks of blood clots, osteoporosis, mood disorders, and cardiovascular events that can result from hormone treatment even in clinical settings.

In the UK, the Tavistock clinic for youth gender medicine was recently forced to shut over concerns for patient safety, and findings that staff were rushing children into procedures they later regretted:

This issue is highly ideological and politicized on both sides. Suggesting medical transition for any minor is not currently supported by the evidence. National health systems like Sweden's have banned it outside clinical trials. Instructing minors to attempt it themselves without medical or psychological evaluation or monitoring is reckless in the extreme. Doing it for sexual gratification, as some are in Keffals' case, is monstrous.
