Yeah a lot of cis people really reject the term. Some don’t like the way it sounds and wants to self identify with a word that they like more… A certain number stick to their guns in wanting to make sure that there is no word that is used for people who are not trans.
Sometimes they opt for wanting to be called “normal” without realizing that there is a value judgement implicit in that word. If you have a “normal man” and a “trans man” you are saying that transness is abnormal, pathologizing gender. You reach the same effect by omission of a word. If there is a man and a trans man then one of these things is assumed standard and the other the deviation.
Of course they don’t see a problem with this because under that model they personally don’t take on the psychological burden of constantly having to referring to oneself by terminology reserved for either the deviant or somehow inferior. To those unused to questioning their centrally held power the idea of just having a word to describe them in relation to others is seen as an oppression.
If enough people disliked the term cis they could band together and just come up with another value neutral word…That’s basically how we arrived at the less science centric terms for other sexuallities like “gay” as an example. “Homosexual” being a relatively new classification wasn’t exactly loved by the people to whom it was applied to beyond their consent as it sounded clinical. Other euphemisms had always existed but gay was purposely adopted as a synonym by the queer community.
I don’t think there would be objection from the trans community long as the term synonymous for cis was essentially was not trying to imply that it is somehow the default state of being.
Think of the potential slang we are missing out on!
Not fully defanged yet. Queer can still be used as a pejorative just like if someone said “That’s so gay!” in the 90’s schoolyard usage to synonym for dumb, uncool or bad… We did however make it kind of harder to pull off as a lot of the time unless you make your tone or context explicitly negative it just comes across as using it in a neutral way.
