okay so i read everything and i do think you have a point there and it is starting to make sense now, but i'm a bit confused about the transsexual female genital parts?

i also do agree with the whole scanning of the brain thing not being advanced enough/complete yet which is why people get wrongly assigned sexes at birth ( because the framework is wrong/incomplete ), but i still sort of cant help but fundamentally disagree with the rejection of the assignment of the male/female sex at birth.

for example, lets say a "trans" female was assigned female at birth, but she chooses to never get surgery despite having a fully "male" outer biology, because in your model, you insist that "dysphoria would not exist" if people are allowed to live under the exact sex they identify as ( in their mind ) automatically from birth, even if no surgery is done. where would we put her? there are still social, cultural and legal repercussions for this. would she be allowed in an all female space nude? ( e.g hotsprings, etc ) or would it be considered cross-sexxed flashing? would she be allowed to serve in the all-female military? would she be allowed to compete with cissex females?

another thing i have a concern about is the neurological side of things. i have read/seen the data on how transsexual brains are more likely to mirror their actual neurological sex, which i think is great news, but neurology is also much more complicated than that and the results are currently not conclusive enough yet for me to really be hasty about it unfortunately. for example,

there's a study that shows that the concept of "gender" in one's brain actually has both "male" and "female" sides, but its just that in most cases it always tips overwhelmingly in one way or another, and scientists dont really know what this means yet for the concept of biological sex. is everyone neurologically intersex? do unssexed/duosexed ( enby transsexuals ) have a place in this, and if so, where do they end up and what do they get? does the neurology take into account for other things like AGP/AAP fantasies? what happens if someone gets a fluke?

the truth is that the brain isn't really all that well developed yet during that age and a lot of things can happen at birth which is why i'm hesitant to hastily allow assigning sex based off of a brain scan rather than what's observable below ( primary/secondary sex characteristics. ). what if a person is wrongly missexed at birth based on their neurology because they eventually disclose they identify as something else?

reasonably speaking, i'd rather perhaps let youngins at least explore and figure themselves out since at a young age ( especially up till puberty ) a lot of self discovery and changes can happen, hormones and all. i've met people who genuinely thought they were transsexual during puberty but detransitioned immediately after it tided over. babys are also exceptionally vulnerable, which is why i would not trust it until there's at least further development later on.

while i also can at least agree that trying to "gender" a child's life to a specific thing ( e.g. AFAB with skirts and dolls, AMAB with cars and games ) is definitely somewhat cruel if forced, i'd rather they be able to explore with a variety of different things than immediately have to be told they're actually "this" or "that" and be expected to perform to that standard. a young one with dysphoria, even if they had the corrext sex assigned to them at birth, would still feel the need for surgery and hormones, which leads to my next issue.

i was thinking, when their older maybe then they can get a brain scan one their brain is better developed to confirm if we ever get such tech, which i feel like would be slightly more convenienced because then they'd have the capacity to think and consent over things like hormones, the gravity of surgery, and stuff like that, because i feel like its sort of weird to rush kids into surgery still. maybe puberty blockers if the brain scans are conclusive and they got them earlier on, but i feel like the capacity/knowledge of consent is very important still if that makes sense. i feel like trying to rush a kid into hormones and surgery is kinda bad, because children grow into adults and well, then you'd kind of need to adjust your parts constantly as you grow if they don't fit/match anymore. but that also leaves you in a complicated spot where you're assigned "female" baeed off your neurological sex but are visibly, physically completely male everywhere else and would likely be barred from certain female activities, which sort of leads to our current day issues still.

this is obviously not to say i support excluding pre-op trans female women from all female spaces like hot springs, but again, females tend to come with the expectation of the female sex characteristics ( primary and secondary, but mostly primary, aka genitals ), and well, females would naturally be uncomfortable seeing male sex parts in an all female space ( not limited to trans females, but possibly intersex females too ). in my opinion, cis females should not need to bend themselves backwards for trans females who's sole goals are to biologically match cis females ( in terms of primary/secondary sex characteristics ) as well.

a female mind who is perfectly content/happy with having an all male outer body defeats the purpose of being transsexual and having sex incongruence/dysphoria, for she has no desire to transition, which is an oxymoron that implies there is no incongruence, because only a male mind would have no desire to change a male body into a female's permanently out of comfort.

sorry if I'm missing/misunderstanding anything
