Seems all your answers have come from women so far OP.
Imagine that. Women. Women having opinions on what we, as a group of, oh let's see, 3,800,000,000 may or may not have in common with a subset of the opposite sex who have very strong opinions on us.
When I reference the other 3.8 billion female humans in relation to myself, when I declare that we are all the same group, you know what I assume about their likes, dislikes, abilities, aptitudes, personalities, behaviour, cognitive strengths, political opinions, clothing choices?
Nothing.
I assume nothing.
I assume those characteristics are as wide and varied as humanity itself. All humanity, male and female.
I'm referencing one thing, and one thing only, about those other 3.8 billion females when I declare we're the same. I'm referencing our biological sex, our bodies. That's all. I'm saying this, and only this: I belong to a group of humans who all developed down the biological path to be the reproductive category that makes eggs not sperm, the only sex that creates offspring. It's a fact. Not an assumption. Not a value judgement. A material, observable, immutable fact, and I don't need permission or agreement or consent to freely observe the material facts of the world in which I exist.
Any other characteristic you could possibly think of is a characteristic of all humanity, not of sex.
And any characteristic of sex, references biology, and biology alone.
We need to stop scrabbling around for completely universal human traits that we can shoehorn into one category and claim as evidence of a common sex.
Female is a state of biology.
