Why Cis not trans??

We already differentiate women and girls to indicate maturity. Men and boys, the same.
Genderist believers need to spend a little time developing terms for the categories they wish to fill, whatever they may be, rather than appropriating the terms already in use for fully occupied human categories.
Transhuman, perhaps. I understand that category is still speculative and quite empty.

Snappity - dogs have no concept of marriage but they can tell men from women.

Cis has a very specific meaning in stereochemistry.
Cis and trans have very specific meanings in genetics to denote the distance/mechanism of action of a promoter element on the gene it acts upon.

Cis should not be used as a prefix to describe women. Woman is the baseline/core/origins definition anyway - it needs no classifier.

The word ‘women’ is just grand as it is. It means adult human females, of the sex that bears live young and produces ova. Nice and clear and unambiguous

I agree. MumsNet should treat both groups equally ie both groups should simply be termed "Women"

But snappity I thought we’d established that humans cannot change sex? So why would transwomen be women?

I agree with Widow. It rarely needs to be used but occasionally is needed to differentiate. No big insult.

Trans woman can be used to differentiate. No big insult.

Hideandgo How about if I identify as 'Hideandgo' and you can be cis-Hideandgo so people won't be confused?

love it!

Agree there is no need for it. I'm sure most people just translate it as 'real' anyway.

Exactly.

It's because male supremacists are allowed to coercively assign but doctors aren't.

Indeed!

That really is the linguistic equivalent of saying that gay and lesbian couples cannot marry because the meaning of the word "marriage" is fixed.

It really isn't. 'Marriage' is a cultural phenomenon, which differs according to place and time. Sex isn't... well, unless you're talking evolutionary timescales.

You can't redefine 'transwoman' as 'woman' i.e. human female because 'woman' is a fixed, biological reality that has global recognition and is understandable in the past, present and future and across species boundaries - a dog that eg doesn't like one human sex will respond to a transwoman as a man.

Oh sure hideandgo and WidowWadman, assume my gender identity why don't you. And commit literal violence..

How do you know where on the gender spectrum other women fall, just becasue they don't describe themselves as male. You can only accurately call them female or women or if you must cis-sex, but then that assumes they are also compfortable with their sexed body which many women aren't, so again, you can only say women or female without making assumptions.

I agree with Widow. It rarely needs to be used but occasionally is needed to differentiate. No big insult.

I don't understand snappity, how do you suggest we differentiate when we need to make it clear we are talking about a man who wants to be a woman?

Mammalian sex is binary and that won't change.

Women are adult human females
Transwomen are adult human males

No confusion there. The transwomen are a subset of men.

Trans being short for transition.
Cis is for isomers.

But we are not the same. Biologically we are different and that biology affects all aspects of our lives. It's biology which causes women to suffer oppression and it's due to that oppression that we need extra protection put in place to try to counter it.

I agree. MumsNet should treat both groups equally ie both groups should simply be termed "Women"

My biology states I'm a woman.

My gender identity if you have to label it states I'm trans

Calling me a ciswoman would be incorrect as I do not identify as female I just am.

WidowWadman Your comment makes no sense.
If all women are women, there cannot be any need to differentiate between us.

It's because male supremacists are allowed to coercively assign but doctors aren't.

Because: oppwession

Cis is not required as a differentiator.

Women.

Transwomen.

Cis is a useful term when differentiating between isomers.
I am not an isomer of female, with the other isomer including male - I am just female.
