You're kind of rambling, so I'm not quite sure what to respond to, but I'll try my best:
1) I never said Conway had a great personality, nor did I bring up her marriage. But you're using a lot of charged language, like "attention whore", and bouncing around in general. You seem to have a strong reaction to this stuff. Might be worth unpacking with a therapist.
2) Would you care to go into detail with the trans people you've met in real life and conversed with? Were they friends, co-workers, strangers on the street, or what? You said "9 out of 10", that implies quite a large sample size.
3) I never said that first-hand experience of anything is required to have knowledge; in fact, you seem to have totally missed the part where I explained how people can learn about things by being willing to question their initial assumptions (which is, like, a core part of science). Are you sure that you're not autistic yourself...?
4) Opinions can be ranked by validity, when the thing we're talking about is accessible in real life. Like, if I was trying to learn about primates, someone who's been to a zoo is more credible than someone who's only exposure is reading "Curious George", and Jane Goodall would be an even better source of information. The reason why Black Holes were a bad metaphor in your post is because they are inaccessible, whereas I (quite clearly, as evidenced by my typing this) am not.
5) lol, "have [I] performed some introspection"? JFC, I don't even know where to begin with that one... uh, the short answer is, yes. The reason why I chose to transition was was to pursue peace and happiness, despite tremendous social stigma. Between the heavy investment in time, money, and energy, it's about as far from a flippant decision as one can get.
I mean, to really answer your big question at: imagine you yourself going on hormone replacement therapy, and experiencing breast growth, reduced muscle mass, atrophied genitalia, and softer skin, among countless other things. Imagine spending dozens of hours getting laser hair removal across dozens of sessions, and losing all your course hair, with only the vellus left, unable to grow a beard or mustache. Imagine risking alienation from your friends and family, or of losing your career. Imagine getting your ears pierced and your nails painted, or spending time each morning applying make-up, and then time in the evening removing it. Imagine growing your hair out below your shoulders, and wearing tight-fitting dresses to parties, and getting called gorgeous.
Does picturing all of that for yourself make you feel good? Do you think you'd be happier, or safer?
If instead it sends a shudder down your spine, then understand /that/ is what I feel when I imagine having coarse hair, or a beard, or those big muscles, or a flat chest, or of wearing a suit and being called handsome. I had all of that stuff for decades, and didn't know how awful it was until I escaped it, because I'd never had another point of comparison. And holy shit am I by every metric happier, healthier, more financially stable, and stronger in my connections to friends and family than I've ever been in my life. An authentic life where I present on the outside how I feel on the outside, and the way people treat me in turn aligns with my sense of self, is just indescribably better than flatly and unconvincingly pantomiming a man.
Realizing you're transgender, and then undertaking a gender transition, is a profound experience that forces one to re-contextualize their entire life, past relationships, memories, etc. It's a real "Plato's Allegory of the Cave" mind-fuck.
