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.
Male, female or nonbinary are a person’s gender.
White, black, asian (nonexclusively) are a person’s race.
Right, left are a person’s handedness.
Gay, straight, bi are a person’s sexual orientation.
Cis, trans are a person’s ________.
Gender modality
Gender identity.
I talked about that in the original post.
Cis and trans don’t really describe a person in the same way as the others. They describe a relationship between characteristics, which none of the other descriptors you list do. You could argue, almost correctly, that cis and trans are part of a person’s gender, but neither one of them is a person’s anything.
Hetero and homo describe a relationship between characteristics. Sexual preference and gender are both characteristics.
