Why does someone's definition of woman matter to this discussion?
You've got this all arse about face. Perhaps you think the order of argument goes like this:
Ooh look. A word, a collection of sounds! Wumm-unn. This sound should probably be a very important one. What possible meaning can we fill that sound with? Let's argue over the wordysoundthing.
Meanwhile, what is ACTUALLY happening is this:
Oooh look. Half of humanity, VERY different from the other half, completely different bodies! Wow, look what their bodies can do! Hang on, why are one half of humanity enslaving the other? Why are they using them like animals? Why are they making up lies about the brains of them being inferior? Why have they made laws to criminalise their bodies? We need a completely unambiguous wordysoundthing that describes the half of humanity that are getting the shit kicked out of them just for being born into this particular body type. Wumm-unn ought to do it. Thank goodness we now have a sound that completely differentiates the two types of humanity by their body types so we can set about pointing out the real differences between the two types, and calling bullshit on the fake differences and unfair treatment! Now we can get to work making life fairer for this particular body type group.
It's not about a competition to fill the word woman with meaning. It isn't:word first, meaning second.
No.
It's reality first, name second.
It's about how desperately opposed some people are to acknowledging the half of humanity that have a certain body type and have always been treated like second class citizens.
See it, but deny it, and make it impossible to discuss it.
What's your visceral reaction to 'allowing' this half of humanity (my half) a word, any word, to describe themselves, if that word distinguishes themselves factually from the other half and throws into sharp relief the real differences between the two halves of humanity?
There are 3.7 billion of us born this way, and we're different from the other lot because of our bodies.
This 'debate' is and has always been a fight to deny the existence of my biological sex as a category worth its own name and rights.
So, fine, don't define 'woman'. But I challenge every TRA with this. Should the half of humanity born female be 'allowed' a single, unambiguous name that relates to their specific biology, and which distinguishes them from the other half?
How strongly do you want to prevent 3.7 billion people from being recognised as a common biological group, with a common word?
