I've been trying to keep up with this thread while trying to programme my wolves, drink my breakfast and barter a lorry... oh, sorry, words have clear definitions, don't they? Walk my dogs, eat my dinner and sell a car.
See how confusing it gets, @SeldomHere when you screw around with what words mean?
Anyway, pulling out the things that especially bugged me...
Why does "woman" need to be a "sex-based category"? Why do we need rigid, socially and legally enforced "sex categories"?
I've already explained that one once. Your brain clearly blanked it.
Because not all people want to be resistricted by your rigid binary and feel much more comfortable with different labels.
It's not 'our rigid binary'.
Sex is biology's rigid binary (with a tiny % of DSDs in the middle, usually leading to infertility). Like it or not, you have the genetic code you have been dealt. I couldn't decide to be a man tomorrow, not when every cell in my body is XX. I could present as a man and call myself Harold and ask people to say 'he', but I'm stuck with the biology I was dealt at conception.
As opposed to your need to impose your linguistic framework on trans people?
See above. You are arguing for full-on PoMo madness here. To suit your argument, you're trying to redefine words which we need, for legal reasons never mind basic descriptive ones. You can't have those words. They are already taken.
The words "man" and "woman" are a social construct, not biological reality.
And the word "marriage" was the name which had been given to a union between a man and a woman for the purpose of making babies.
The words man and woman describe material reality, the sex binary (see above about biology). Marriage, as you seem to be failing to realise, describes something that people created and that people can, therefore, change. I am not the only person on this thread to make this basic observation to you
And in response to me asking, fairly politely, not to be called 'cis':
Can you desist from saying "transwomen" instead of "trans women", and from policing whether trans women are referred to as women?
You're the one changing the rules and the meanings, not me, so it's up to you to convince me that you're right and I'm wrong. You're not doing a very good job of it so far.
