Absolutely knock--down brilliant post, Materialist.
I wish it were a blog post so more people could read it. Seriously, I would make it the gender-critical manifesto if I could.
If we accept the TRA terms of debate, we've already submitted to the authority of the TRAs. We've already conceded everything.
This is so crucial for feminists to understand, if we are to have any hope of winning this fight. We must not allow trans activists to continue dictating the terms of this debate. We must go on the front foot, and start defining our own terms, both linguistically (refuse to use trans Newspeak) and rhetorically (don't let TRAs continue to frame this as being about the 'rights' of a 'vulnerable minority', don't concede things that aren't true for the sake of compromise, and don't waste our time and energy getting defensive and trying to prove that we aren't 'bigots').
I've said this before: we should be challenging them to defend their supremely illogical ideology, which is totalitarian at base, which is resulting in to real harm to women and children, and which is going to wreak serious damage on the whole of society if it isn't stopped. 'Gender identity' doctrine doesn't make any sense, it's just a mess of sexism, homophobia, wild contradictions and thought-terminating cult mantras. Feminists could make a lot of headway, I think, if we went on the offensive by Telling Everyone Real Facts about how incoherent and harmful trans ideology is - all of it, not just 'self ID'.
This is a head-to-head clash of men vs. women over just which sex class has authority over the very being of women. It is the absolute essence of the patriarchal struggle.
That's it in the starkest terms. And that's why terms like 'trans woman', 'transgender woman' and 'transwomen' are so damaging, and why feminists will continue to lose if we use them - because they fundamentally disguise what the essence of this struggle is about.
