It seems to me that breaking the link between physical sex and gender role/behaviour is a necessary and important first step in dismantling it.
That's not what the doctrine of gender identity does. On the contrary, it reinforces sex stereotypes and sex role stereotypes by claiming that membership of a sex class depends on an individual's preference for one set of stereotypes over the other and not on that individual's actual sex.
And that the fracturing of gender roles into 100 different genders or whatever only further weakens an oppresive gender binary, not least because it is no longer a binary.
It doesn't do that either, because most of these identities are unknown and unknowable to the vast majority of people, thanks in part to their ever expanding number and endlessly changing nature. In order to address and remedy the oppressive nature of sex stereotypes and sex role stereotypes, society needs far more than trendy identity creation based on mere personality traits. Especially since the genesis of those identities arises for the most part and rather firmly from those very stereotypes.
Does that mean in the future people will not still face oppression because of sex at birth, or even that more feminine type people will not face oppression from more masculine type people - I don't know, but I think it's worth a try.
We've danced this dance before, jj1968 and I understand that although sex stereotypes and sex role stereotypes have harmed both of us, your experience and mine are profoundly different. I do also understand why you put so much faith in this doctrine and what you hope it might achieve for those males who do not conform to the stereotypes associated with their sex.
Like many others, I have been disadvantaged and discriminated against on the basis of various characteristics - my parents' socio-economic status, my nationality and immigration status and my sex. I have been able to escape or mitigate the effects of the others, but most of the inequality I have suffered on the basis of my sex remains inescapable. Even though I did not comply with the stereotypes imposed on my sex from early childhood and have actively resisted them since teen age, the specific issues that arise from my sex being female cannot be resolved by my gender-non-compliance. Because stereotypes are not the root cause of those issues. My sex is.
When we say that sex is the root of our oppression and gender the tool, that doesn't mean that we can end that oppression by destroying the tool. It's a way to say that in a male-dominated world the stereotypes associated with the female sex serve a specific function that the stereotypes associated with the male sex do not. Can we improve the lives of female people by eliminating stereotypes? Absolutely. Can we eliminate our oppression by eliminating stereotypes? No.
So no, it's not "feminine type people" who are oppressed by "masculine type people". If that was the case we could all just identify out of being oppressed by adopting masculine stereotypes. Believe me, I've tried. That is an axis of discrimination specific to males who do not conform to the stereotypes associated with the male sex. The same axis exists for us, of course, but it isn't the main one.
I've come to understand that no matter how much they may have suffered themselves and no matter how empathetic they are to our suffering and how willing they may therefore be to fight for my rights, no male person can ever truly comprehend what it is like to be born female in a male-dominated world. And that stereotypes are only part of the problem we need to overcome. So I certainly don't expect you to accept or even understand why transgender ideology and legislation is something that I find it necessary to resist as yet another expression of the patriarchy that harms all female people. But I would like you to consider whether those you seek to protect really will benefit from destroying women's sex-based rights.
(And a side note on "oppression". That word has a specific meaning - systematic abuse, exploitation and injustice - which is in my view applicable only to inequality suffered on the basis of race, sex and class. So I do not accept that when feminine males are discriminated against this amounts to oppression.)
