What are cis and trans alternate types of? I don’t think it’s “gender identity” because wouldn’t that just be man, woman or nonbinary regardless of whether they’re cis or trans? Cis/trans just being a qualifier?
If the answer is “I am cis” or “I am trans”, what is the question?
Edit: Someone came up with the term “gender congruity” and (after looking up the definition of “congruity”) I think this describes what I’m talking about perfectly.
There is no such category. Being cisgender or being transgender describes the relationship between 2 variables. The first being your assigned gender. The second being your gender identity. Cisgender means there is an equivalence of those 2 variables. Transgender means there is not an equivalence of those 2 variables.
The reason we use the term trans which means roughly “other side” to describe this is because you cannot know you are transgender at birth. Your gender identity is assumed to be cisgender, it is assumed to be the same as the gender you are assigned. So when you reveal your gender identity to in fact be something different you are moving to another side of gender. At least in literal usage of the terms cis and trans.
