In my parent’s generation, being left-handed was seen as wrong and actively suppressed. Even as a child, I was often looked at skeptically. I was a “Southpaw”, a term I can now go years without hearing. As a teacher, some of my immigrant students have looked askance at me, but other than that, it’s just not an issue anymore.
When I was a child, it was a common discussion whether someone dyed their hair, especially blondes. “Natural blonde” and “bleached blonde” were part of the daily active vocabulary of the culture; now, they’re much less common. Very few people care anymore.
When I was a teenager, it was scandalous to talk about a same sex partner. Now, meh, in pockets of the country, it still is, but the culture as a whole is more accepting. And so while “straight” and “gay” are still part of the English language, they’re not generally part of daily conversation. People are people.
That’s the end goal for transness as well: That people only discuss whether they’re “cis” or “trans” when it’s relevant, which is rarely. Support groups. Memoirs. Personal reflections. Certainly not when discussing other people. But… when people in 2024 (or 2023, or 2022…) reject “cis”, they’re not usually doing it because they want to move to the post-issue world where being trans isn’t shamed and oppressed. They’re doing it because they want to move back to the pre-issue world where being trans is fully closeted.
We’re in the tunnel now, moving from one cultural state to the other, and we’re not going backwards. If people want to stop having “cis” as an actively discussed term, they need to stop treating us trans people like some broken anomaly. Accept us as fully human, and “cis” will fade away naturally.
