The kind of “girl” that a boy who identifies as a girl thinks he is

We have on the one side an explanation of male and female based on genetics that we could describe in a few words to an alien

and on the other side, we have a concept of male and female that can not be described to native speakers of English ?

I think you’re rather lost here. Asking whether gender incongruence might exist in a hypothetical world where a child is raised by wolves and never encounters another human being is (a) an impossible question to answer and (b) of little relevance to the world we actually inhabit, where human beings develop within social relationships and societies.

You seem to have conflated three entirely separate questions: whether gender incongruence exists, how we understand its development, and what constitutes appropriate clinical care for children and adolescents experiencing it.

Of course we have a responsibility to ensure that clinical interventions are evidence-based, proportionate and informed by a careful assessment of potential benefits and harms. But that responsibility has absolutely nothing to do with whether someone can answer your hypothetical question about a child raised by wolves.

Yes. And I've seen some of the messy videos uploaded to social media. It's a very tragic case. And of course Susie Green is still making money out of doing the same harm to other children, despite the NHS warning:

'Anne Trans Healthcare Ltd
Anne Trans Healthcare Ltd is a UK based company, though its clinical team is based overseas. It is not registered with the Care Quality Commission.
It describes itself as “a subscription service which coordinates therapeutic and medical support for individuals experiencing gender incongruence through referrals to healthcare professionals”. It offers access to overseas healthcare professionals, and its website states that it offers services which include “puberty blockers for individuals of all ages, including those under 18.”
As has been noted above, and subject to narrow exceptions, the sale or supply by private prescription of GnRH analogues to children and young people under 18 years for the purposes of puberty suppression and as a treatment for gender incongruence and/or gender dysphoria contravenes the Government’s restrictions on their prescription and is contrary to the aims of the NHS clinical policy position.
The company’s published terms and conditions has the disclaimer that “Anne is not responsible for the quality of care, advice, or any prescriptions or medication provided to you/the Minor (if applicable) by any Independent Healthcare Professional”.'

The aetiology of a condition is an interesting and important scientific question, but it isn’t necessarily the most relevant consideration when determining appropriate treatment, particularly when we’re a long way from establishing definitive answers.

We don’t have a complete understanding of the aetiology of all sorts of conditions, but that doesn’t mean we can’t or shouldn’t treat them. Someone close to me has recently developed Parkinson’s disease, for example. We don’t fully understand its aetiology. Does that mean she shouldn’t receive medication to manage her symptoms? My youngest child is autistic. Do I know the precise aetiology of her autism? No. Does that mean she shouldn’t receive the support she needs?

Clinical decisions are informed by evidence about a condition’s presentation, prognosis, and the potential benefits and harms of available interventions. A complete understanding of its aetiology isn’t a prerequisite for providing appropriate care.

And as for your hypothetical about a child raised by wolves, I’m not sure what you think it would establish. We might ask - would a child raised without human contact develop language? Almost certainly not in the ordinary way. Does that tell us that language has no biological basis, or that it isn’t a real aspect of human development? Of course not.

Human development involves complex interactions between biological processes and social experience. Even if we could establish whether a child raised by wolves would experience gender incongruence, that wouldn’t tell us whether gender incongruence is real, whether it has a biological basis, or what constitutes appropriate clinical care for people who experience it. At most, it might tell us something about the role of social experience in its development

From that description, I have no idea whether your child is male or female. This is not helped by the nonsensical convention that "trans boy" means someone female who claims to be male and "trans girl" means someone male who claims to be female. I don't know whether you are following this convention or not.

Your thought experiment doesn’t drive a coach and horses through anything. human development involves complex interactions between biological processes and social experience. Language is an obvious example. A child raised without human contact wouldn’t develop language normally. Does that mean our capacity for language isn’t innate, or that language is simply a social construct? Of course not.

You’re also presenting a false dichotomy between biological and social phenomena, as though something influenced by social experience cannot have a biological basis. That’s a fundamental misunderstanding of human development.

Finally, even if you could establish that gender incongruence was entirely socially determined, which you haven’t, that wouldn’t in itself tell us whether pharmacological interventions were appropriate. That question requires evidence about their effectiveness, risks and benefits, not assumptions about whether the underlying phenomenon is biological or social

I haven’t suggested that understanding aetiology is unimportant to medical research. However, understanding of a condition’s aetiology isn’t a prerequisite for providing effective treatment.

I have no trouble believing in gender incongruence. As a child I felt alienated from the more feminine portrayals of girls and women. I used to make up boys’ names for myself and wear my brother’s clothes. Thankfully, I grew up in a time where being a ‘Tom boy’ was perfectly okay and no one suggested I was trapped in the wrong body. George from the Famous Five was my role model. When I reached puberty I (eventually) made peace with my physical body and embrace my femininity. In my view, inventing the ‘solution’ (surgical and hormonal treatments) has created the problem (and the market). I am straight but it’s well established that a childhood feeling of gender incongruence is more common and stronger in people who will grow up to be same sex attracted. I’ve seen this play out in children I know in two ways. Either they are allowed to express themselves freely and they grow up as gender non-conforming and same sex attracted, or the adults in their lives decide they are trans and they go down that path.

Her child is clearly assigned female, but told her he was a boy age four, and is a trans man. That's clear from what she wrote. I'm not sure why it's not clear to you?

There are very ,very good reasons why society shouldn't just "accept" most importantly the medicalisation of gender questioning children, leading to harmful hormonal and surgical interventions, creating lifelong patients. We absolutely do "need to understand" - seeing as the trans umbrella covers everyone from teenage autistic girls who may be struggling with hormonal mood disturbance ,sensory issues around periods and finding themselves same sex attracted, to the middle aged married-with-children cross dressing men to trans school shooters and paedophiles. If it was a case of just accepting that people have differences in ideas and experiences of gender identity ,most of us could be on board with this but sadly it's not.

That's not gender incongruence. Thats (at most) gender non conformity. Tonnes of women / girls have that experience, I certainly did. It's not the same thing at all as being trans.

How do you know?

but told her he was a boy age four

Told a friend she was a boy. Let that sink in. A four year old girl told another four year old she was a boy and Lo! she's a boy from then on.

And somehow it’s us who are wrong for “not getting it”.

from her description. That description doesn't describe anything like the experience of gender incongruence: it's a description of a very ordinary and commonplace reaction to gender norms/ roles/ stereotypes.

A four year old girl told another four year old she was a boy and Lo! she's a boy from then on

Are toy suggesting you really believe that's how simple it was in real life? Come on be serious now,

What she appeared to write is a tale of a woman who found it almost impossible to relate to having a female child. Something she appears to relate to being ‘a feminist’. But sure, parental interaction with children has zero influence.

She was simply trying to explain that she wasn't into gender stereotypes and that stereotypes had nothing to do with her child being trans.
