WDNS I think this is the whole crux of the argument really.
The (predominating, toxic element of the) trans movement claims that "innate gender identity" is a real thing, and in fact more real than biological reality. They are saying that they really are women because they identify as women, and mere biology is just a smokescreen hiding the unarguable truth of their womanhood.
They have managed to manoeuvre things so that they seem like the least privileged, most oppressed group of all, and because they have twisted things so fundamentally, the oppression of women - having its roots as it does in our biological reality - is completely discounted. We have the almighty "privilege" of having our "gender identity" and our biological sex align, and that's all anyone could ever ask for, right?
They can talk with a straight face of "AFAB privilege" ["Assigned Female At Birth"] because they have remodelled the worldview to make this the only thing that matters; they have positioned us as the power holders who must be challenged and ultimately stripped of our "unjust" exclusive access to our female only spaces, and in so doing deny the continuing reality of women's oppression, of our real place in the power hierarchy, deny the reality that we have and we need these spaces because we are the LESS powerful group, not because we are the power holders!
I have actually seen trans rights people comparing their demand to use women's facilities to Rosa Parks sitting at the front of the bus.
And nearly all the people you would think would see right through this have been completely taken in. Despite the fact that there is no real hard scientific evidence to back up this belief in "gender identity", while the biological differences between men and women are a matter of simple fact. Despite the fact that the oppression of women by men is still a universally occurring phenomenon and should be a source of shame and concern for liberal western democracies, and yet it pales into insignificance beside the oppression of trans people by non trans people.
It's the most extraordinary sleight of hand. If we speak up against it, instead of being a vulnerable group trying to protect ourselves, we are transphobic oppressors, bigots who must be shamed and silenced. The absolute denial of biological reality, of the extent of women's oppression in the world we live in - that goes unchallenged.
We're not the white guys stopping Rosa Parks sitting at the front of the bus! We ARE Rosa Parks, and we're still sitting way, way way at the back of the bus, as this whole situation demonstrates.
Those men, with their testicle-based testimony, are listened to and believed, while we with our untrustworthy, originally-sinning female gonads are treated with contempt and suspicion. Our evidence here doesn't even get accorded the weight of the half a man's evidence that it merits in Sharia law.
And we've got the MRAs saying feminism has gone too far.
