Whenever I've heard a suggestion that I should just live as a feminine guy, it just makes me feel sick. Even in a world where no gender stereotypes existed, I wouldn't want to be male. I'd rather not live the rest of my life with a masculine face, body hair, a flat chest, male fat distribution, etc. My transition has nothing to do with social roles and everything to do with my body.
Before I transitioned, I actually had problems recognizing myself in the mirror. It wasn't until I'd been on hormones for half a year that I could actually remember my face.
Also, my own hobbies and interests are more androgynous than anything else, but I probably lean towards being more gender non-conforming as a girl than as a guy.
It is unclear to me as why it contradicts the social construct part of the gender.
Maybe some people negates the physical difference between women and men, but I doubt that it is the majority of people that believe that the social part of the gender is socially constructed.
I don't understand that the fact that you couldn't stand being in a man body (I'm sorry for that BTW and glad you "escaped") does not invalidate the belief that the gender side associated with pink and blue, or which kind of job is socially constructed.
