I find it strange that many people here are against this when the alternative is a surgical treatment that often can’t be easily reversed, and even when it is, often lowers the likelihood they will have a kid.
Chemical solutions are way better in that regard because if they are done right they don’t damage any tissue and their affects are temporary.
Cis isn’t a slur the same way trans isn’t a slur, they are words to describe those particular gender identities and/or gender modalities.
I’ve heard it used in hostile contexts but I’ve also heard trans used in similar contexts as well. That doesn’t make these words slurs, they are descriptors used in a context that is hostile.
Yeah the amount that it’s offensive is dependent on the context, but that’s really true of any descriptive term. In those contexts it’s the insults or animosity that determine offensiveness, not the descriptive terms.
I.e. “those dirty fucking cyclists” in this phrase which would be offensive to cyclists it is the insult and the animosity that make it offensive, not the descriptive term itself.
Obviously it’s different when you use actual slurs to describe the person but in the situations described with use of cisgender that usually isn’t the case (there are slur uses of cis but they’re rare and not used much, therefore have low recognition).
