I will answer that last question as a female who think she understands where butterfly is coming from
Being a woman is in reality more than just our biology
It's also how society chooses to interact with us based on its assumptions which are based on its assumptions on what biology we possess
This is important. If it was just biology without social things there is no reason we would get paid less or excluded from parliament
The discrimination we face is purely societal
We fight against this but it is there in every interaction we ever have
If society thinks you are biological female it treats you different on average
And that is an experience that in turn affects who you are , your behaviour is a reaction to that treatment
And your reaction isn't determined by your genital biology , so there is an aspect of being a woman that isn't determined by your biology directly. In that if you had male biology but suffered the treatment that women suffer , you would probably react the same way
So today girls may be discouraged from doing maths , boys encouraged
So many girls will give up maths even if they are good at it . You gave up maths not because of your biology but because of how your biology led others to treat you. Other girls may continue , with an additional streak of determination ... you need to be mentally stronger to succeed so you learn skills and resilience that the boys don't need to
If the situation suddenly became boys being discouraged, then many boys would give up
So the way society treats you shapes you as a person in a way that is actually independent of your sex and I think that is the aspects of womanhood that butterfly is holding to
Remember that butterfly by very transition has shown herself more susceptible to societal influence than others who resist
