"Cis" and "trans" are different types of a person's.... what?
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.
Society does not create sex. Society creates gender. Gender is a social construct. Sex is an expression of your sex chromosomes. The genitalia you have at birth weren't decided upon arbitrarily by everyone in the room, they're a direct consequence of whether you have or lack a y chromosome.
Money is a social construct. That doesn't mean coins and dollar bills don't exist. Sex is made up by society. Genitals are a physical thing. But they're not the same thing. Just like coins and money are not the same thing.
You're confusing sex and gender. Sex is a function of biology. It is binary. There are two sexes, and which sex you are is wholly determined by presence or absence of a y chromosome.
Gender is a social construct.
This is the entire reason that the term transgender is used now instead of transsexual.
Also, your whole analogy is shit. The concept of money didn't spring into existence because people already had coins. The coins spring forth from the concept of money. By your logic, we only have genitals because society got together and decided that we should all have a sex.
That is the stupidest idea I have ever heard in my life, and Ive read several tweets from Donald Trump.
Do you think sex didn't exist before 1912? It seems like you are confusing sex with the rough approximation of the shape of a chromosome and oversimplifying how those chromosomes relates to phenotype.
Trans people change their sex, not their gender. Trans men are men before they start taking T and trans women are women before they start taking E. What changes is their sex. Personally, I hope we see transgender replaced with something soon. Transsexual is fine as a subcategory of transgender people (or a category with lots of overlap with transgender people).
Social constructs don't all originate in the same way. If you want an example more like sex, you can look at the social construct of race. Race is not skin color, but the social construct is related to things like skin color. Just because race is a social construct doesn't mean skin color came after race.
