you understand that studies have shown that being trans is supported by mainstream science, right? Like, trans women's brains match female brains more than male brains, and vice versa with trans men? No one is trying to argue that biological sex isn't real, it's just only a part of the story for some people...
No, that's a misunderstanding of the studies, begaydocrime. There are several studies that sought to examine whether the brains of female-to-male and male-to-female transsexuals were closer to the sex they identified as than their own. (These studies looked at the minute structural differences between the brains of male and female people.)
They didn't show that. They did show that transsexuals were closer to the opposite sex than people of the same sex, but they remained closer to the latter than the former.
Just to illustrate, an example below (which represents the way this worked, not the actual results).
Draw a line. Label one end with 1, the other with 10.
Position 1 is the male control group and position 10 is the female control group. These studies found that male-to-female transsexuals would be located between 1 and 3, while female-to-male transsexuals would be located between position 10 and 8, i.e. each transsexual group is positioned closer to their own than the opposite sex. And that means they did not match the opposite sex more than their own.
Furthermore, the studies I looked into all featured homosexual transsexuals who had medically transitioned by taking cross-sex hormones at the very least. This presents two problems as to whether the observed position of the transsexual group was a result of:
- the subjects' homosexuality and/or
- the subjects' use of cross-sex hormones
There is considerable overlap in what comparative neurological studies show that look into differences between the brains of homosexual and heterosexual people and those looking into possible differences in the brains of transsexuals. That overlap needs to be carefully examined before any observed difference can be attributed to either transsexualism or homosexuality.
There are also studies that have shown that in those suffering from gender dysphoria, there is an area of the brain that is similarly affected to the brains of people with eating disorders and other body dysmorphia. That area of the brain governs perception of the self, and of course it makes sense that someone who wishes to have the body of the opposite sex would have that region be particularly active.
I don't doubt that neuroscience will deliver some much needed answers in this field. In the meantime, it's always good to read the actual papers and check the methodology used and the limitations the authors themselves place on their results.
