'Cis[whatever]' means 'Non-trans[whatever]', essentially. 'Non-trans' is an incredibly awkward phrasing; there is already a way to say that, and it is 'Cis'.
I wonder, in the more right-wing-aligned US universities, do history lectures have to talk about Julius Caesar being made governor of Non-Transalpine Gaul, to avoid offending the snowflakes by using the Forbidden Prefix. Cislunar space? Surely you mean Normal-lunar space, praise be to Musk.
1. Words describing concepts you don't like are "slurs". Would you say that "genocide", "murder", "mobbing" are slurs, too?
2. Merely using a word means "forcing an ideology". If I talk about a genocide, would you think that I am trying to force my ideology (which would be... I guess an ideology of genocide, somehow)?
Do I get that right? I'm genuinely trying to understand.
The way I see it is this: there are people in the world who identify themselves with a gender that differs from their sex societally designated/assigned at birth. That is not an ideology, that is a fact. Instead of using this whole sentence when referring to them as a group, the word "transgender" (or "trans" for short) can be used. It is just a descriptive word.
Now if someone wants to refer to the group of people who are not trans, they can say "non-trans". I don't really see that as a word, but rather as a language construct ("not trans"). Instead of saying "non-trans", one can say "cisgender" ("cis" for short).
In my view, those words just describe factual groups of people. I genuinely don't see how they force an ideology (what ideology would that be?).
