No, i’m not “cis” i’m a fucking woman. sorry if my proclaiming of being a female is “offensive” - you don’t get to NAME me.
I think the issue here is that you want to continue being the unmarked identity. Trans* women have been Othered by society which, yes, is patriarchal, but the Othering is by no means carried out exclusively by men. People’s have brought up various “radical feminists”, for example, and the Michigan Womyn’s Musical Festival.
But here’s the thing. Being the unmarked identity? It’s a fucking privilege. It means a word exists to describe people who aren’t like you, because they are not “normal” like you are. It means you are the default. And that is a privilege. For years, so many different words existed to describe trans* women - slurs, medicalized language, the trans* community’s own colloquialisms - but there was no adjective for what you are, because what you are is what every woman was assumed to be. That is a privilege. So now, there is a word to describe people who are not part of this marginalized group. If you don’t identify as something non-cis (usually transgender, but not always), then the label that applies to you is cisgender.
The people who need to be able to refer to what you are and they are not are not your oppressors, not in matters of gender. We are talking about a marginalized group, a minority in every sense of the word, who, when people do decide to acknowledge their existence, are seen as not-women because their womanhood has always required an adjective, because they are always the Other to your unmarked, because they have never been seen as simply “women” as you always have been, they have never had that privilege.
To reject a label that marks your unmarked identity is to deny the privilege that you have in not being Other, in not being trans*.
