Nope.
Gay people didn't redefine anyone else's marriages. They just wanted marriages that allowed for the two people in a specific marriage to be the same sex.
Trans people, by contrast, require that every other human being in the world reassesses their own identity to align to the neo-sexist genderist beliefs that that "real" differences between women and men are mental not physical, simply so that they can inhabit some sexist fantasy of being the opposite sex.
And yet, female people do exist. And whether you allow that these people are the real bearers or the name "women" or not, nevertheless being female is still real and still has consequences.
We are the half of humanity born female. And we live with that, the physical reality and the social consequences, the good and the bad, from the day we are born until the day we die.
Our knowledge of ourself is formed within the knowledge of what society constructs around our bodies. It informs how we are treated and so how we understand ourselves.
In other places and other times, we have been property. We have been banned from education, from economic freedom, from cultural and political power. From telling our own stories in our own voices.
The shadows of that, of the history of people with bodies like ours and not yours, of the stories society constructs around our bodies and not yours, affect our freedom and our status even today.
There is a clear line of descent that can be drawn between the history of female people and women's rights, protections and challenges today.
This is not the story and reality of whatever it is that trans "women" think is womanhood. It is the story and reality of us. Of Female people.
And I think that matters. Regardless of what trans people may or may not suffer, I think the reality of female existence matters enough that we should be allowed to keep our own name and our own identity as the female half of humanity.
I do not think that whatever it is that trans people feel to be true about themselves is so important that it justifies un-naming and de-historying the most consistently marginalised and exploited group of humans there is. It does not justify redefining our lives and our history as something else that you find more accommodating to your needs.
If redefining other people wasn't at the heart of it, you would not be so desperate to stop female people having our own identity and our own name and our own voice and our own history.
You know it and and I know it. The fact you cannot bear us to exist without you says everything.
Find new words to describe this thing that is not physical sex, because physical sex still matters enough to enough people to bear its own name too.
