The legal team for the foster mother/mother according to the judgement rely largely on the report of Dr Pasterski.
This is the position of Dr Pasterski on childhood GD:
In her report she identifies that there have been recent changes to the diagnostic criteria for gender dysphoria and that research on mental health and transgender children have shed light onto critical historical misunderstandings related to clinical presentation in gender dysphoria. Firstly, that children who present with gender dysphoria are likely to desist in their cross-gender identification and secondly that gender dysphoria is inherently associated with high rates of comorbid psychopathology. She notes both have been shown to be false. She identifies that these misunderstandings arise from two particular factors. Firstly earlier studies which showed that up to 80% of children desist in gender dysphoria included children who presented with gender incongruent behaviour but did not necessarily state the wish to be or that they were the other gender. Thus children displaying gender variance may have been wrongly diagnosed with gender dysphoria. As a result of this treatment protocols previously incorporated a watch and wait approach which had prevented truly dysphoric children from transitioning which had likely resulted in increased rates of depression and anxiety. As Dr Pasterski puts it 'Put simply, many who have shown to desist were likely not dysphoric and psychopathology in those who persisted was likely due to forbidden expression of their true gender identity.'
This is not the current NHS position. (Quite aside from the usual No True Scotsman fallacy as used by gender evangelists day in, day out). This extreme position has been recently challenged both by a review at the Tavi and by TV documentaries such as Panorama.
Why did SS withdraw in the face of this? Why is the family court accepting QCs arguing this extremist view?
