The treatment of gender dysphoria is no different to the treatment for other kinds of mental ill health, for which the initial offerings are also medication.
This is a very good point.
Many medications for mental health also come with very unpleasant side effects where the benefit is weighed against the impact of those effects - albeit these are not permanently life altering ones such as a permanent removal of fertility or capacity to be a full and equal participator in a sexual relationship, and possibly permanently preventing full brain and body maturity every occurring. (Not yet known, this is still emerging.)
However anyone working with children with mental health needs knows how very very reluctant professionals are to move to medication, and how much other strategies must have been tried first and proven not to be successful. And that it is very rare for children to be medicated or even seen to be considered for medication below a certain age regardless of severity of need.
It is the fixed belief that 'transition is the answer' rather than being able to look more holistically at a child - and to do so in itself is seen as an intolerable act of transphobia. This fixed and extreme belief in transition being the one true and only answer - and better to transition and accept some children will later wish they hadn't and be harmed by it - than to miss the children it would help, is in itself the barrier to more thoughtful, careful, less invasive treatment.
It has become politics led. Not needs led. With the drive being to serve the adult agendas within the politics and not primarily to do no harm and meet the needs of the individual child. Over and over in the whistleblowing accounts it is mentioned how much the centres became owned, directed and controlled by political lobby groups instead of remaining independent. The capture is the problem. This should never have been permitted.
And frankly the TQ+ political agenda would be in a far, far stronger place now if they had resisted the urge to capture and control, and instead trusted that the results would happen independently of them to prove that they were right. Interesting that they did not have this trust.
