I wouldn't call your posts 'rants' at all, Zandax, they are very interesting and thank you for sharing your thoughts and experience.
Having had a very gender-confused childhood I recognise a lot of what you say.
I think it throws up a lot of questions, though - it all seems to comes down to the concept of 'feeling wrong', which is so personal and indefinable..
It wasn't that you wanted to play with Spiderman rather than Barbie, it isn't that you want to conform to masculine stereotypes instead of feminine ones...
It seems to come down to an essence of 'boyness' or 'girlness', which transcend gender stereotypes, and you feel were issued with the 'wrong' essence, and you describe the fall-out from that as a 'crippling sense of wrongness'.
I felt something similar when I was growing up. I'm sure a lot of it was because being a boy seemed to be an easier and more exciting way through life, but actually I didn't necessarily want to be a boy, I just knew I didn't want to be a girl, and didn't want to grow up to be a woman.
It never occurred to me that there was an 'essence' of boyness or girlness, it was more which team you had been selected for, and I felt that the girls' team was definitely non-league
Pragmatism won out when puberty hit; fortunately for me puberty blockers, transitioning, etc were unheard of at that time, so I worked out my own way forward in life as a gender non-conforming lesbian woman.
As such, I always have a slight inkling of regret when I hear of a woman changing her body from a woman's body, the kind I like a lot, to something resembling a man's body, which I don't like at all...
anyway, thanks again for your posts!
