The women promoting transition.

Women have all sort of opinions and ideas on different issues and topics.

Women are just as capable as men in acting out of self-interest or because they don't directly experience certain issues and so therefore don't see why it would be a problem.

I think feminists in general need to move away from thinking there's some default stance that all women will 'naturally' gravitate to simply because they are women. The vast majority of women don't view themselves as feminists anyway even if they might agree with feminists on certain things.

It's important to hold women responsible for their actions and stances rather than sweep it under the carpet as them being 'brainwashed by the patriarchy'.
Women have agency. Respect that.
They have the ability for intelligent thinking. With freedom comes accountability, so critique their ideas, engage and debate with them. A woman isn't going to agree with you simply because she is a woman. If you have a robust argument, it should be possible to persuade someone to see your side of the debate irrespective of whether they are a woman or a man. They might not agree with it, but you should be able to state the reasons for your position clearly without having to resort to appeals that she should be on your side because she is a woman too.

Most trans rhetoric doesn't make sense, no matter the sex or identity of the ideologue.

I think these women are so entrenched in misogyny they don't even see what they are doing to themselves. I know that sounds patronising but I genuinely think they don't know what they are doing. It is the women like Hines who ACTIVELY and gleefully attack women and use this ideology to do it who are truly treacherous.

Why should you feel like the sex traitor? To me it feels just the other way around: that they are the sex traitors. I, too, cannot understand why any woman would support her own erasure. They are, indeed, the women Dworkin refers to.

Do any of the women you cite identify as feminists, though?

And, speaking generally, identifying as a feminist is not really the same as being one, if your practice harms women.

But also, it seems to me that feminism has always been a broad church with different strands. Neoliberal feminism will of course support individual choice in a market place where the self is commodified. Others would argue that commodifying the self does harm to women as a group and therefore is not feminist.

I do not think there is one agreed definition of feminism which remains static over time and place.

The point about feminism being literally about castration - surely the counter-argument is simply that feminists such as Sheila Jeffries (hope I have that right?) have argued against transition from a feminist point of view for decades and that the first sex change operations were done by men (Johns Hopkins Institute, if I have that right) who talked about gender identity before feminists even picked up the concept of gender.
