So, trying to pick up a few of the points raised again:
@sanluca "Positrans, your own copied words show very clearly that they think there might be something, but there is no actual evidence."
The article is all about how there is now enough evidence for science to proceed an the basis that gender identity is biological. Is it proof? No, but proof is rarer than you think in science - they generally look at the evidence they have, even if incomplete, and draw preliminary conclusions about what that evidence likely shows.
@OldCrone "Most of the studies are on people with DSDs, not transgender people. The studies are small. They say that the conclusions should be interpreted with caution because of small sample size. Also, some of the 'biological' results were in MTF transgender people who had been treated with oestrogen or FTM transgender people on testosterone."
I agree with all of that, but it is still strong enough for the scientists to say "Considerable scientific evidence has emerged demonstrating a durable biological element underlying gender identity.1, 2 Individuals may make choices due to other factors in their lives, but there do not seem to be external forces that genuinely cause individuals to change gender identity." And note the the actual existence of gender identity isn't even a question - it's a given.
"The reference list this time is up to 13, and it looks as though they are all different this time."
Yes, the evidence is growing all the time, and it's all going in the same direction.
@TyroTerf "The implication being that the normal human developmental pathway involves identifying and adhering to the sex stereotypes relevant to one's body type."
Again, being trans is not about sex stereotypes, it's about gender identity. That's why some trans girls are tomboys:
www.newsweek.com/transgender-kids-living-identity-develop-cis-children-1471729
""Within both transgender and cisgender children, we find a wide range in the strength of their identity and preferences. For example, we had some 'tomboy' transgender girls in the study, just as we had 'tomboy' cisgender girls.""
@Winesalot "Thanks oldcrone. Seems quite astounding that the NHS Tavistock could not access or provide such evidence that this 'august medical institution' has stated definitely exists and in quantity."
There will be more court cases. This will all be overturned. In the meantime, most of us are contributing what we can so that the affected children can get the blockers they need.
@gardenbird48 "the mahoosive industry that is forming off altering the bodies of transgender people"
If trans people get blockers at puberty, they generally need a lot less surgery. Also, transition resolves most of the mental health problems so if the medical industry wants to make money out of trans people, it's more lucrative for them to have a psychiatric patient for life (typically £250 a session for a private gender specialist), than a happy patient who needs nothing more than HRT. That's one of the reasons we want self ID - so we can stop giving our money to these people.
@Datun "You wanting a certain cohort of males/transwomen/y-chromosome people to have the right to shower and change with teenage girls/female children/elderly women, adult XX chromosomed people isn't happening. "
It's already happening - has been for years. It has been interesting to learn that communal changing rooms still exist. I thought they died out in the 70s. I don't know why you would want to get naked with a bunch of strangers, and I don't know why you would look at their genitals, but here's the thing - if you do glimpse a woman's penis, be it on a trans woman, or perhaps on a woman with the highly virilised form of adrenal hyperplasia, you won't actually die.
Also, given the prevalence of sexual assaults in women's prisons and the existence of women like Becky Reid who starved, beat and then murdered her girlfriend, I would be wary of sending my teenage daughter naked into a room of naked strangers, even if it was exclusive to people you would define as female.
