A re their more than 2 genders?

[Master Raiden]

Why? I don't see any reason why someone's biological sex should align with how they see themselves socially. There are certainly no ethical obligations.

I just don't see gender defined as how people see themselves. I see it as identical to biological sex. I guess I've always associated the word 'gender' with that.

Why? For now at least, behavioural differences in men and women are statistically significant. It objectively makes sense to describe "feminine" and "masculine" attitudes and traits. But even though biological sex is a strong predictor for these kinds of characteristics, as it happens it's not perfect. Hence it makes sense to have some kind of description, separate from biological sex, of how people exhibit or identify with these attitudes.

I would love it if men and women didn't have these differences, but as long as they do, I think many people will find gender a useful concept for communicating how they feel they fit in.

What are some words you would use to describe feminine and masculine behavior? Why can't you just use those words instead? Describing someone as either male or female based on their behavior isn't as specific.

I think you've missed the point, what you've written is bordering on incoherent. You just said "gender and biological sex are identical" and then are baffled when that view doesn't actually make sense (of course the gender you identify with doesn't change your sex, because gender and sex aren't identical rofl).

I said "gender roles", not "gender". Having the behavioral traits of a particular gender should not mean you are that gender.
