Terfinator - living as a woman is medical terminology used by doctors in the RLE - Real Life Experience - test that they impose on anyone seeking gender reassignment.
Or at least did in the days when things have not been blurred by not wanting to offend people.
I doubt any transgender person perceives it in the way you seem to think. It is just the exam we have to pass before anyone gets approval for surgery and then to get a Gender Recognition Certificate.
In my experience in the early days all doctors and surgeons involved in this field were men and imposed their ideals onto their patients. They were in some cases the very people many radical feminists perceive as being the trans patients doing this - wishing to create stereotype ideals from their own imagination.
That's what these doctors did - they would usually only further those patients they believed would 'pass' and would offer ideas of dress and make up from a male perspective.
I saw this early on and would do what it took to shut the guy up and then got on with being myself and acting as I wanted. It was an accommodation.
Happily there are more women doctors and surgeons today in general and in this field so that old school attempt to mould trans women in male doctor's image is less prevalent. But might still be a factor.
The trans women I know from those days have blended into society pretty seamlessly in many different roles. As diverse as any other women in relationships, style and appearance. And in a wide range of occupations. We really are not seeking to follow a pattern. We are just being ourselves in the way that I would have thought Feminism would champion.
We have brought a lot of diversity whilst being perceived by those around us as women, regardless of whether you think we are. Because until very recently most of us did not announce ourselves as trans or fight for rights or make a song and dance about being special because we are trans.
This is a creation of the post millennium generation, social media and much wider definition of what transgender is away from the original one of transsexual.
We all just settled quietly and happily into finally being ourselves and got on with life hardly ever thinking about being trans. Events around us have forced us to speak out and defend ourselves in ways that just were not necessary until very recently.
Despite having published 50 books and made radio and TV show I personally never wrote or spoke in public about trans matters once until about 3 years ago when this all kicked off. Now I seem to do it all the time.
As for describing the feeling that makes us reject biology and none can do it and it being built around stereotypes. I empathise with your frustration and understand it because, believe me, all my adult life I have been trying to answer the same question to myself.
Unfortunately, it is just one of those things that is indefinable because it is a nagging, gnawing sense of self within that just feels at odds with the perception of that self from others around you. At first you presume this is just a part of growing up. Then you realise that body and mind just seem like halves of two different people and your mind drives you to adapt the body to match.
I know that sounds bland and diffuse, but that's how it was. It genuinely feels innate. I do not know if it is or not. Only that I knew something was wrong from about 3 or 4 and more or less what was wrong by about 8. And from then on it was a quest to put right what I perceived as an error of biology.
It was not about clothes or toys or playmates or any of that because I had a brother and no sister, so was not envious. But equally I was raised in a happy family with no real restraints on what I did. So I could have quite easily coped by being myself if it was all about things I wanted to do or wear or who I wanted to be with.
In many ways it would be much easier if it were that simple. I would just tell you and let you draw your own conclusions.
You likely will anyhow. But I cannot make things up to persuade you. I can only tell you what it was like. And I am as baffled as any of you as to how and why it occurred.
Because - believe me - no child would choose to be trans. It is something that nags at you like a pain in your inner core that just never goes away and pushes you on and on to find a way to make things right. Nobody wants that to take over their life and I can well understand why in earlier times so many trans kids will have self harmed or attempted suicide. It is deeply distressing o your whole sense of being.
