I'd say natures presentation of gender is more profound than what the ego displays.
Your voice is a female one, and that voice would be the same if you were born in another environment with different people, tastes, preferences and experiences that make the ego itself. How we act, or how we're expected to act will never determine our gender. Transgenderism is just a term, while in an autopsy, the observer will determine the human specimen's gender on natures terms.
The world can say Bruce Jenner is a woman, but seriously we'd be deluding ourselves with ignorance and make belief.
When I see Blanch, I think that's one of those Bieber boys, And I'd totally think she's a dude. But if nature produced Blanch as a female, then she'll be a female no matter how tomboy she is. ( Physically Blanch looks like a boy to me, down to the composure ) Some women have that build, flat chest, no curves, but they still have other feminine attributes (except for Blanch).

Women are intended to be caregivers. This is the case among all mammals. It would be dangerous for an infant to have to wait till Mother came home to be fed. Women produce the milk for our children. ( Drinking cows milk is also unnatural. We consume it because others make money off of it, the cows milk is cancerous and was meant to turn caffs into 800lb bulls. )
First wave, feminism was founded by the world bank. Rothschild. Now more people pay tax than ever, and the rich get richer. More and more people are single, a vast amount of women want to focus on their career and have children later, or never. The world is being formed so people will look to the government before they do family, because traditional family is on it's way out.
I think career based women are miserable people.
