there is a division of gender based roles and expectations (a whole new rant is available on that grin) and I feel more aligned with a number of aspects of one of those than the other.
Well yes! That's personality. It's not innate to a particular sex.
You get gender nonconforming men and women, all the time. So much so it makes a slight mockery of people thinking that most people are gender conforming. Therefore it can't be predictor of sex.
It suits a patriarchal society to make women conform to a feminine gender. To do the unpaid housework, the emotional, and sexual labour. To be objectified (porn, prostitution, the media portrayal of women). Women's role was to provide sex on demand, as evidenced by the law only changing for marital rape in 1992.
Women showed how capable they were during the war. The country had to rely on them for everything as the men were away fighting.
It's no coincidence that the 1950s housewife is a trope. After the war men wanted their jobs back, and the women were reluctant to give up their new found independence. So the government went on a massive marketing exercise to get them back in the kitchen.
When you look back at the newspaper/magazine ads, etc, and the heavy media input into what makes a woman, it's fairly shocking. And you are left in little doubt as to the patriarchal expectation of women's roles.
Until you can remove that, no one will know whether or not sandwich making or sewing labels/buttons is an innate characteristic usually confined to the female sex.
(Which makes me laugh, because how come all the top chefs are historically men, and so are tailors).
