Mmm...espo, I think the problem lies in that a prompt to change who we are mentally by any degree and/or means is exactly what we had to (and to varied extent still have to) cope with knowing we DON'T want. An idealogy that inevitably goes along the lines of 'Why transgender?!' gets offensive even under the kindest wordings and kindest intentions.
Anyway, I would like you to please explain what you mean differently beween 'blue pill' or 'reassign'. ^^; Your definition of reassign gender is designating that we reidentify ourselves into a cisgender equivalent of ourself, right? That's...exactly what the 'blue pill' approach is, change our mentality from what it is as a transgender into being a cisgender version. I find that thus there's no honest difference after all. It's mostly a 'difference' from that reassignment doesn't call up the same stigma as 'blue pill' in this, so it seems different.
Either way, apparently there are methods to try to harmonize the mind to the body, rather than the body to the mind. I was prompted by my therapist when I first met her on which one I was asking her to help me accomplish, so evidently it's real. Furthermore I have an online contact who took the route. Just like transexual persuit, it's not set up perfectly yet: In this case, he still deals with his transexual mind trying to wake up.
I'm glad you understand where we're coming from, though. ^^

Also, I have just realized something that may be critical to realize. A lot of thoughts from people who aren't transgender think of ->-bleeped-<- as an instance, as well as the body being a presence. In terms of this, an 'instance' is always exclusive in its existance to the current moment, and a presence not only is present in the current moment but present in its history.
...This is actually the other way around: ->-bleeped-<- is a presence, and the body is an instance. At any given point of time, your body is always as it is in the moment. You're not male/female for any length of time in your body, despite your history, it's merely that your body has continued to hone its instance into its state: History is technically absolutely irralevent to the body's design.
Personalities, however, work as the continual presence. In so, you are not changing "I am a woman/man" to "I am a man/woman"...rather, you are changing X time of the statement "I am a woman/man" being spammed out, x being the time since the brain was developed. If you try to do it without countering the entire history of the statement, you give the mind a very severe culture shock of sorts to work with, and unlike culture shocks that are external...you drop it right on the mind itself. The reason it culture shocks is because there's a drastic change in the environment the brain functions under, so previous standards can no longer apply, and it withdraws information to use from a standard that literally does not exist. (A transgender woman's brain wouldn't line of thought 'this is how a man does it', but rather 'Ok, this is how I, a man, do it' only to realize '...erm...wait, I never was a man though o_o' because it recognized everything it did as a female) ---This all comes off as really dangerous to me. ^^;
On top of that, this is a kind of trait that's not just a particular statement, but furthermore 'coats' the history of the personality as well, because of what it is as a trait. Everything a transgender does and has done essentially is a woman/man who's been doing it, it's just that the representive of their choices is not the same as the person who did the choice..So you're not just telling the mind to argue "I am a man/woman" in some form but also "A man/woman is what did and thought everything previously, not a woman/man". Otherwise...culture shock from the inside again.
Technically I guess a scientist of sci fi poportions could give amnesia and replant the memories 'properly' to prevent an internal culture shock. but even if that were possible, the brain deals with hormones the same way as the body, I'm sure: No matter how masculinized/feminized the hormones develop the brain, the base brain itself HAS been a woman/man. Just like a MtF's bones don't turn into a woman's structure with estrogen exposure, I severely doubt that it's possible that the brain would have genuinely changed to its male/female counterpart despite its developments' continuation.
I feel this is something worth consideration for this kind of question
