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.
If sex is a social construct as you claim, you have an incredibly easy position to support. All you have to do is show me one verified example of a non-ectopic human male pregnancy. If you can do that, I will concede on all points and incorrectly say sex when I mean gender, just like you do, for the remaider of my life.
That’s how confident I am that you don’t know anything about this topic.
