The NHS made some serious errors when they agreed to permanently damage the bodies and fertility of healthy humans who believe that they can 'transition' from female to male or vice versa.
Doctors aren't McDonald's, obliged to fill your order no questions asked. They have a duty of care to patients to establish whether a treatment will IMPROVE the health of that patient, and an obligation to ensure that the patient has full capacity to give informed consent.
Oh, and they have a duty not to lie or mislead patients.
If every patient was given the correct medical information there wouldn't be a generation of permanently damaged people realising they haven't become the opposite sex after all, they've just needlessly and irrevocably damaged their bodies.
When female teenagers turn up to see a GP insisting they are male inside their head because of how they think, they need to hear no-one is male or female in the way they think. That male and female is a matter of body, not mind, and not yearning. That hormones will damage you. That surgery will damage you. That none of it will change your sex, and none of it will bring happiness, and that you'll spend a lifetime as a patient futilely trying to force the entire world to agree with you on something they can plainly see isn't true. And most importantly, that children do not have the capacity to consent to the enormity of this change and it's lifelong health consequences.
"Positive affirmation" is utter dereliction of duty.
