Grabtharshammar I found your posts incredibly helpful and crystallised something I've been trying to find words for.
One is that the research in this whole area is really small, and one article or even 10 proves nothing either way, its the collective weight of the body of knowledge that matters - and we're not there yet, either from a science or a social science perspective. Yes, lived experience matters but personal stories and journal articles are different types of discussion.
The second is that I was given a book for Christmas called "We are our brains" by Dutch neuroscience researcher Dick Swaab, and there were a few pages on differences between "transexual" brains (quoting his word) and others. It was a small sample size but you can read that and think, ok, there's a basis for further research on those lines. But brain science does not then determine a social response - because actually our brains are not everything, the rest of our bodies matter and so does history and society as it is now. Women aren't raped or put in menstruation huts because of their brains.
Further: Swaab's research is 10-20 years old, and reading it I became clear that even 10 year old science cannot be mapped to our social debate today. He was talking about m2f being 1 in 10,000 of the population and f2m being 1 in 30,000 - which doesn't map onto the huge increases of young girls at the Tavistock for example. The transgender umbrella wasn't an organising concept when that research was carried out, therefore any research about people diagnosed with gender dysphoria 15 years ago cannot be used as an input for policy changes in response to the "transgender umbrella". If there was an MRI scan that could diagnose gender dysphoria, that would be huge. I would be delighted to see more research on the area, and I cannot fathom how the Tavistock can be taking on such a huge volume of young, vulnerable patients when they know that the research base is so thin, and results from older studies not relevant to the huge uptick in young girls presenting at the clinic now.
But also I saved that cartoon because that said it all far more concisely than I have done!
