This argument leaves me so cold. If you have a distressed child, regardless of the source of the distress, if there is a medical treatment pathway that requires taking drugs for life and potentially irreversible life altering surgery, and a non medical pathway that could see distress relieved via other mechanisms such as talking therapy, the default should ALWAYS be the latter, with the former considered only after non medical approach has failed.
This theory of sacred 'inner transness' needing to be realised is so toxic. This is a metaphysical belief, just like the existence of God it cannot be tested, so there is no possibility of proving or disproving this theory. Gender affirming care is religion rendered as western medicine. These are distressed, confused v likely gay kids. A small number may benefit from transition, but the vast majority, with the right support will be able to live happily in their bodies.
