I don't "identify" as "cis". I think of myself as normal, pretty much like everyone else. But when I need a word to describe myself as "not trans"... There isn't one, until "cis" came along.

So yes, I'm "cis". I don't like the word, and I probably would not have managed to come up with it on my own. But "straight" doesn't describe the situation and "not trans" is inherently negative, where no negativity is desired.

I'll fully agree that I don't follow a lot of the stereotypes for my gender, but there are a lot I do follow, too. Nobody is 100% stereotypical. And Cis- and trans-gender isn't even about that. It's about how you feel and who you feel you are, not about following stereotypes.

so the reason I use that adjective is because it only has upside. It is effortless, harmless, actually briefly conveys a much longer abstract message which is the purpose of language, and helps otherwise marginalized people feel included and stay productive.

it doesn’t matter to me that 99% of people already match that adjective which wasn't previously known or necessary
