It looks like you've used the forbidden c-word in your answer. I am not sure what you mean in this context. You've included trans women and women who are not transgender. What is this third class of women?
I don't think I understand the question. Did you mean why did I divide Women into trans and cis, a framing which as a gender critical person you wuodl expect me to reject?
I was in this context speaking specifcally of people who actively identify as women - ie not all people who may use the word Woman, which as you know includes many who use it as its original sex based meaning, but only and specifcally those people who explicitly claim for themselves to experience a gender identity as a woman. Taking that group, there are those who identify as trans women and those who identify as cis women and that's all, no third group. Which of course is exactly why I and many others avoid using the word Woman for myself unless it's clearly the sex based meaning not just for me but also for the recipient, to avoid it being mistakenly assumed that we identify as cis women.
I don't mind that you don't think you have a gender identity.
I don't have a gender identity. If you really need to fit me into your framework I am an agender female, although I'm not sure the genderist framework can accomodate that (which incidentally is why I am so sure it is flawed). And FWIW I do mind that you, a male person (1), believe you have better insight into firstly, my own identity, and secondly, into how female people experience being female, than I do.
A trans-friendly way of discussing reproductive rights is to use the term AFAB or AMAB
The "A" bit is an issue due to the ideological assumptions behind it, but I'm not going to go down that derail here.
What is interesting about AFAB is that I have recently noticed some high profile female bloggers and writers who have always been vehementally TWAW are starting to talk about the experiences/injustices of "AFAB" people - not limited to reproductive rights but their wider experience of abuse, encrochment and belittling by AMAB people and by society's sexism - describe themselves as "AFAB" or even as "non-binary AFAB". I've always thought it might go that way, as people for whom professing TWAW was a key part of their formative identity as a young person age into adulthood and encounter the annoyingly sex-based realities and injustices of our culture. TWAW is so fundamental to them they can't use the word Woman, and yet they are starting to find they need it.
(1) Up til now I always thought you might be a trans man. I'm kind of disappointed, would have been good to have a trans man's insights on womanhood and manhood.
