'And now suddenly it is upon me to provide all the worlds evidence ? I don't mind passing on the info which I found and look for more. But as this is public info, anyone can find it.'
Do you understand that you are making statements that you cannot support with evidence? Do you understand the harm in do this?
If you cannot support your statements with evidence, after looking, have you thought about why that is, and why you have believed what you have said? You actually said:
'scientific understanding of genetics, but next to that is also the biology and the process of development. The scientific definition on transgender people is that in their development, the brain developed in a way that it does not match the body'.
Do you understand why you are getting the response you are getting?
There are no neurological markers for being transgender. The only commonality shared by all people with a transgender identity is a philosophical belief. It is also a philosophical belief that does not reflect material reality.
For instance, there is a taxi driver study (and I cannot find it, maybe someone else can though, this board is loaded with information) that shows brain scans of people who have the same interests, such as driving and memorising the streets of London, have similar brain scans. They also have identified that male people who are same sex attracted are likely to share similar brain scans.
Hormones have a significant interaction with the brain and this will show up on brain scans. Even when taken exogenously.
The study you posted did not control for same sex attraction in their group. They also stated that those male people with gender identities did not have a 'female' brain scan. So, if a brain develops different patterns due to interests and repeated actions creating different responses, then of course male people with interests that they consider 'female' because they are different from stereotypical male interests, will have scans that group. And if they are taking exogenous estrogen then the brain scans will also differ from male scans who are not taking estrogen.
But they are not female brains.
So, no. Male people with the philosophical belief that doesn't reflect the material reality of their body (even after extreme body modifications) are not born in the 'wrong body'. That is their wishing to have a different body. That is fine, but no one should be expected to act in ways that affirm that.
