@audreyharrison answered: Maybe because some people want others to know that they are trans*/cis and others don’t, so it is as identity for some but not others.
I'm not sure I understand... the way I use "identity", it means something you know you are, whether or not others know. I think the way you're using it is the way I'd use "presentation" -- IE what you show others of yourself. So you can certainly present as cis to some and trans* to others, but, idk.
I guess I don't get it because I feel one's identification - meaning here one's knowledge of oneself as cis or trans* - derives immediately from knowledge of one's assigned-at-birth gender vs. one's actual gender, where one's actual gender is an identity thing... am I making sense at all? but like, one's presentation is another question entirely.
...actually thinking of my own experience: I present as a cis woman, I identify as agender... and while it follows that I would be trans* that really feels wrong to me since I still have basically all the cis privileges ever. So maybe you are right after all.
