> If we define women as "everyone who defines themselves as a woman", what exactly is a woman then?
I agree. If we open things up so widely, then terms like "man" and "woman" become meaningless. Nevertheless, it also doesn't seem right to be to disregard the experiences of trans people.
My preferred way out of this conundrum is to view gender as multi-dimensional. As such, there are multiple kinds of woman (and man). Three important kinds might be:
1. Biological women. Which we can define in different ways: it might include only people who were born women, or it might include people who have altered their physiology either through surgery or hormones. It might include some intersex people, or it might not.
2. People who "feel like" a woman
3. The political class of women: those are identified by others as women, and treated differently on that basis.
If one wants to define "woman", one then has to be clear about what kind of woman they mean. At which point it becomes relatively straightforward. As a linguistic convention, I would suggest:
- "man"/"woman" can be informally used for any of the above categories
- Where possible, or is asked to clarify, people should be specific about which kind of gender they mean.
- Nobody should claim that "man"/"woman" refer only to one kind of gender.
I would eventually like to get to the point where people have separate identities in each category, which is already how I approach my own gender identity. I identify as biologically male. I don't have feelings of gender, so I identify as non-binary or agender in that category. And I am usually but not always treated like a man, so I mostly identify as male in that category, but not entirely.
I feel like this is a lot more useful (and inclusive!) than a binary "are you a man or a woman".
