A final point that everyone keeps mentioning, not every trans woman or trans man wants to be identified as transgender. They don't wish to use the term outside of speaking to medical professionals. So if you don't like the term cisgender then respect that trans women are women and trans men are men. And if you don't have a gender identity that by definition would mean you are transgender.
I'm not going to post this for the particular benefit of the OP, who has already said she has to work now, but for other visitors wondering what might be wrong with this.
This was the perspective that sent me off to "educate myself," nearly ten years ago as a TWAW liberal feminist. I had noticed a tendency towards the assumption that gender stereotypes predicted gender identity. I said that I was "cis" (I know!) but I prefer a masculine dress sense, enjoy male-dominated hobbies and feel no alignment with an inner sense of male or female. The first response I had told me that I might be cissexual, but was undoubtedly transgender.
Oh.
Okay, I thought. Perhaps I am. And I went off and duly researched everything I could get my little paws on. Some of it I enjoyed (I liked Kate Bornstein's autobiography) but the rest brought me to a screeching halt as I realised that so much of what I read was phenomenally sexist.
I was being told that if I enjoyed men's activities and preferred a masculine appearance, I wasn't really a woman. That real women (or "cis women") were those whose inner selves magically aligned with the sexist shite expected of them in patriarchy - how convenient for patriarchy! Real women, whatever their birth sex, just innately sense themselves to be the kind, pink, endlessly enduring and patient helpmeet to the innately superior male. Fuck. That.
I don't have a gender identity - I conducted a genuine and thorough search and concluded I don't feel an innate sense of gender at all. In fact, I came to the view that this innate gender stuff was a religious view. Realising that saying this to others would mark me as a heretic was a particularly discomforting experience. I am not transgender because I think gender is sexist bollocks designed to uphold patriarchy. And as a longstanding trans ally I was perplexed by the idea that validating me as unwoman would do any level of service to those for whom the laws were designed.
So for me at least, this "by definition" is part of the problem. I ignore gender expectations because they are reductive and limiting, not because I am transgender. My mode of dress, hobbies, preferences and mannerisms are part of my personality - remember those? It's what we used to call our sense of self before that idea was replaced with a computer generated drop-down menu of pick 'n' mix identities - and do not denote my subscription to anybody else's quasi-religious beliefs.
