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.
Sex is not binary, or intersex people wouldn’t exist.
You can also have XY chromosomes and be assigned female at birth.
And transsexual as a term has not gone out of usage universally. It’s got nothing to do with sex and gender both being socially created constructs. It’s preferential, and some people still use it.
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.
