I need to bring up something that's been bugging me.

We talk all the time about how sex isn't just genitals, it's every piece of our being. If you look into it, even our non-sexual organs are genetically dimorphic between men and women.

The inconsistency to me though is when we say there's no such thing as a female brain. All of a sudden, all of the femaleness that is intrinsic to every other part of who we are becomes invisible. I understand that we don't want to lend credibility to the idea that TIMs can have a "female brain," but even the research that exhibits sexual dimorphism in brains doesn't show that--in fact, while "trans brains" are mildly shifted towards their "preferred gender," they are still well-within normal ranges for their sex, and still outside the average range for their "identity." It's not a gotcha, and I don't think we need to be afraid of it.

The graphic on this study (under Results) is especially good to look at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8955456/

If anything, I think admitting that female brains do exist (with some variance within the sex, of course) and that TIMs do not have them is perfectly good evidence for being gender critical. (And for those who criticize lesbians for not sleeping with TIMs because we're genital fetishists, well, no, the brain plays a part too. Suck on that, "hearts, not parts.")

Some might call it sexist to say there are differences between male and female brains, but I think the it's more that the sexist conclusions that people come to as a result of the difference existing are problematic--ie: because "female brains" exist, women must be more predisposed to doing housework, or some other nonsense.

Also, when we talk about puberty blockers being harmful because of the importance of sex hormones in adolescent brain development, I think it's a bit willfully ignorant to not assume that estrogen and testosterone might have different effects on the brain.

Prove me wrong, please, or give me another way to think about it! I just think it's something worth tackling head on, rather than brushing aside.

I've seen it abused by TIMs who say "the brain scans of some males show patterns more similar to those of females, not other males, therefore this proves they are women in mens' bodies."

Men are, on average, taller than women. Yet many individual women are taller than many individual men. So this is the rhetorical equivalent of saying "this man if 5'4, and the average height of a woman is 5'6, while for a man is 5'9. Therefore, this man is actually a woman because SHE is 5'4."

Yes, sexual dimorphism is real - and one facet of this is that, since most health benchmarks and therapies are normed for men, we are under/misdiagnosed and not as well treated. The problem is when it's turned into a scientistic factoid by TIMs to 'prove' their point.

I increasingly think the lesson is just not to argue with people incapable of good faith, rather than try and either explain or oversimplify reality, which is complicated but still doesn't prove you can be "born in the wrong body."

Theoretically even if there were blue and pink brains, and the pink brain was born in a male body, it doesn’t mean born in wrong body. If this hypothetical situation was real it could just mean that human species has developed to the extent female brains can be in male bodies and vice versa. Like x men shit. Even if it were real it doesn’t mean they need to mutilate their bodies or use spaces for the opposite sexed body. We don’t pee from our brains, a female brain in a male body doesn’t need the female toilets.

If it were hypothetically even possible.
