> Trans people aren't trying to tell cis people that their physical bodies aren't allowed to matter to them
I feel like they are.
Specifically, if you believe that "feeling like" a gender makes you that gender, then it seems to me that logically you have to believe one of the following:
(1) That having the physiology associated with a given gender is not sufficient to count as a gender.
This invalidates the identity of people like me who don't experience the "gender feeling" that trans people (and some cis people) talk about, and therefore base their identity as a man/woman on their physicality.
OR
(2) That gender categories are "open" where for example either feeling like a man OR having "male" physiology makes you a man.
But that seems to make the whole concept of gender pointless because people with penises don't share anything in common with people who feel like men (that they don't also share with people who feel like women and people with vaginas) unless they happen to be people who fall into both categories. It also makes it impossible for someone express that they have one of those things but not the other because there is only one label "man/woman" to describe two distinct phenomena.

If you have a suggestion for how someone like me who has male physiology but doesn't have a "feeling of being a man" (or any other gender) can represent themselves in a system where there is only a single gender identifier and making sub-distinctions is frowned upon (because "trans (wo)men are (wo)men") then I'm all ears.
