Helen8220:
So the only way to get to a place where people are truly free from gendered norms and expectations (or at least, free to adopt them or reject them as they wish) is to detach the concepts of ‘man’ and ‘woman’ from biological sex and allow people to inhabit them as they wish.
No this is not the only way. There is another (obvious and better) way.
It is this: detach the concepts of ‘man’ and ‘woman’ from gendered norms.
-- Or, perhaps, which is equivalent: detach gendered norms from the concepts of ‘man’ and ‘woman’
That will be much simpler. And we will not even have to rewrite the dictionary.
[" woman: ... an adult female human being." (From OED.)]
It is, perhaps, useful to see the divide between us in such simple terms, Helen8220:
Some of us wish people (men and women, boys and girls) not to be defined by gender norms, thinking as we do that that has been, and remains, a mechanism of oppression. Others you for instance really really want to emphasise the way people have been so defined; indeed you wish this to be reinforced.
Can you see why we might say, 'No, thanks'?
