It doesn't need to be 'decoupled'. They are very very very much related, so much so that they are sometimes virtually synonymous. Like most stuff on the planet, there are rare exceptions, like when multiplication and division rules sometimes get all ◊◊◊◊◊◊ up when using zero, infinity, and 1, and we have to carve out exceptions.
I wholeheartedly agree. That's kind of my point. Any time we go to talk about gender in any meaningful, practical way, we actually end up talking about sex. Every time a heterosexual male is attracted to a transwoman, it's because he mistakenly perceives them as female. Any time we talk about trans rights in public policy, we're actually talking about rights relating to sex. Any time we talk about treating someone like a woman, we're either talking about literally nothing, or else we're talking about something extremely sexist and regressive.
Sure they can. Gender is the expression of sex roles. It's not binary (men do dis, women do dat). It's not even a spectrum with masculine on one end and feminine on the other. It's some kind of Cartesian coordinate representation, maybe with a z-axis, where cishet tomboys have a range that has overlap with butch lesbians and transmen, all fairly close but distinctly different. How do I represent that more precisely? Don't know, don't care. I can guess right in the overwhelming majority of times, so it works for me. I don't need an oversimplified standard that would make me a total dickhead unless I'm posting on X.
None of the gender expressions ("expressions of sex roles") you're talking about have any practical applications at all. Your definitions of "sex roles" - tomboy, butch lez, etc. - have no real use. As soon as your society moves away from restricting women's participation on account of their sex, this whole notion of meaningful sex roles becomes completely irrelevant.
Putting anti-discrimination laws relating to gender in a weird place of irrelevance?
I have addressed this in the past. Gender identity is a belief system and/or a personal preference. I wholeheartedly support not discriminating against people for their belief system or personal preference. If someone wants to present as their inner concept of a "woman", that shouldn't preclude them from getting a job, buying a home, etc. But there is nothing about gender identity that should entitle anyone to special privileges not enjoyed by other members of their sex (such as the privilege of overriding sex segregation).
You use the example that i have repeatedly said is the rare exception: it doesn't matter in most social interactions unless you plan to bone the person. Otherwise (medical, prison, competitive athletics aside), I have dead zero interest in other guys' dicks. Managed to go my whole adult life without the slightest interaction with them. Just doesn't matter. But it matters a lot how I interact with people every day, based on their presentation. They could be smooth as a Ken doll down there, as far as I know.
My point is exactly that it doesn't matter in any social interaction that isn't about sex.
In what meaningful way does your interaction with a male change, if they present as a woman to you? Is it the same way you interact with females who present as women? Do you not treat everyone the same, regardless of their sex or gender presentation?
Practical applications will always be disparate to the social experience. Murder, for instance, is illegal. Not really a concern to my everyday life. If someone is going to try to kill me, they will probably do so with no regard to law. So rather than codifying public policy, I'm checking my personal weapons inventory, because the personal interaction is loads more significant than some policy wank's wet dream.
The above should clarify. If you find it unsatisfactory, I'll address whatever you find lacking.
We have a substantial corpus of public policy, defining what is and isn't murder, various degrees of severity of the act, a number of closely-adjacent acts, and a range of penalties depending on the details and level of involvement in the act.
And no, the above does not clarify. You
still have not explained how you treat women differently from men, in any meaningful way.
