The thread has been derailed a bit about whether cis is offensive. It doesn't matter whether individual people can see that it is or not (although Ego has made it pretty clear that she does understand that it is offensive).
I am female. My cells are female. I've never not been female, so I don't know what other things make me female - biologically, and chemically, I have XX chromosomes and am female. I look female, I have boobs and feminine features and long hair, but I'm pretty sure that's a byproduct of being female, rather than what makes me female. I work in a "male" job, in a "male" industry, but that doesn't change things either - I'm still female.
I struggle to understand, therefore, how can you want to be female. It isn't really anything. Publicly, at least, CJ seems to equate being female with dressing glamorously and wearing women's clothes and lingerie, wearing lots of make-up, being flirty. I could name 5 women straight off that I've never seen wearking make-up or in a dress. The two don't equate, being a woman is more than that.
In any situation, it feels insulting if someone switches from the privileged side to fight with the underdogs, failing to recognise that they were privileged. Like pacifists who have others fight and die for them, and then proclaim that they were wrong, whilst enjoying the freedom that the fight won. It's not just a gender issue, in general, we're annoyed by this. I can't enter the paralympics because I'm able-bodied, I have chronic conditions and might well identify as a disabled person, but I'm not. They wouldn't let me race. I also can't enter the man's race, and I can't run for Germany, because I'm not German. These are facts. I don't meet the criteria so I can't do them.
It feels like these are the two most important facts in this argument. What is it to identify as female, and how is that possible without the XX chromosomes? There is no way to get those. Rationally and logically, the sense that something is wrong, that it doesn't fit, has to stem from something. You can't miss chromosomes that you never had. What is it to identify as female? How can it be anything but superficial, and how can that not offend women, who are much more than superficial?
And for people who do think that they don't belong with their biological gender, do they automatically become part of the side that they do identify with? That's not usually the case in life. I can't decide to become black, or Spanish, or run in the paralympics. I could set up a semi-lympics, I could move to Spain, but I can't join those groups because I'm not one of them. I am uncomfortable with the idea of a biological male being able to access some women's spaces, like women's wards - I've been on them hugely vulnerable and whilst I don't believe all men are attackers or rapists, if you're having gynecological issues, having men around is an extra complication - or rape centres. We had a women's only society at Uni to discuss the issues that affected us because of our biological gender - having a man there would be changed that. You can apply it to anything, from women's football teams to changing rooms and birthing classes. Women's prisons.
If our pronouns and spaces are taken over by people who don't identify as male, we are disadvantaged, again. I have no problem with people changing their own pronoun, or gender, or acting however they wish. I'm not sure that means that they can change my position, though, and branding me "Cis", or taking my pronoun, or using my spaces, does.
I am not cis. I am female, because biologically that is my classification, and I've never been anything else. I have no idea what it is to be male, apart from the obvious differences - I imagine careers are easier and having a penis could be fun, but I have no real idea.
Mumsnet is actually a brilliant example of this. Although it's an inclusive parenting site, it's aimed at Mums, at females who have reproduced. I don't fit into that category but I'm welcome here, as long as I respect the site. The same is true of the men here. But you'd expect that MN would stand up for it's core audience, wouldn't you? You can guarantee that if there was a MansNet, they'd be vocal about their issues and anything that they felt threatened them. Being women, we just take it, for the most part.
And that's before you debate whether it is actually possible to be wrong by referring to someone as their biological gender. It is a fact. That would, I believe, be enough in a Court of Law. You cannot libel or slander someone with a true fact.
