Hello. Interesting stuff, intelligently presented. I'm not your enemy. I would add the following:
(1) Biologically you're male. Biology is a hard science and science is not in doubt that human beings with XY chromosomes are male by definition. Your natural phenotypal expression further confirms this.
(2) Metaphysically you're female. You're responding to the feminine archetype as you see it incarnated in the society around you and you say to yourself, "That's reflecting what I am inside." Your transition is about making your phenotype match your metaphysical identity, which you have learned about by observing the heterosexual dynamic all around you.
(3) You and all transsexuals are therefore defying feminist dogma that says that all human beings are psychologically identical, modified only by lived experience. If you didn't deny it, at least implicitly, then how would you know what "girl" even means, and why would "girl" have such an important meaning to you?
(4) How do you feel about transableism, the psychological condition whereby someone feels the deep need to amputate their foot, for example? Would you consider such a person mentally ill? If not, what about someone intentionally blinding themselves, or killing themselves? If so, why is amputating a foot insane but amputating a penis not insane?
