It’s only complicated if you start from the premise that language must accord the same importance to the experience of small minorities as to the experience of the overwhelming majority.
I don't want to focus on the outliers. I want to focus on the fact that we're enforcing a binary distinction when there are outliers.
If you argument is that there are more than 2 genders, that's fine, Man, Woman and whatever else.
They are outliers that have their own names.
Certain things are constant though Man: Adult Human with XY sex Chromosomes
Woman: Adult Human with XX sex Chromosomes
Everything else and I mean no disrespect with this term, are mutations that fall outside of the norm.
Surgery and hormones though do not change your sex chromosomes. You are still sex you were born as. You can be a trans woman, but sex wise you are still a man and vice versa for trans men.
I wish trans people all the happiness in the world but if you paint stripes on a horse its still a horse, not a zebra.
Why not? Why can't the outliers try and fit into the binary definition we enforce on society?
The idea of a person of one sex displaying common gender characteristics of the other sex is very old.
An adult human is a fully mature member of the species Homo sapien.
An adult human female is a fully mature member of the species Homo sapien who belongs to the reproductive class that produces large, immobile gametes. The reproductive system of an individual may be actual, potential, historic or broken.
How do you define “woman”?
“Proves” in that saying means “tests”, not “establishes the validity of”.
The legal maxim only makes sense in its domain because it rests on the idea that law is written by people, and that calling out a specific case for one treatment reveals a pre-existing understanding that outside of that case, that treatment would not apply.
Let's say you have concrete definitions of man and woman (and as many additional categories as you please). You see a person and believe they fall into one category. As it turns out, you are wrong, and they are actually in another category.
That you miscategorized someone has no bearing on the validity (or lack thereof) of your definitions.
In principle, this is not necessarily true in Ovotesticular DSD (formerly “True Hermaphroditism”), which is generally a symptom of tetragametic chimerism, though for both health and gender reasons it is apparently not uncommon for people who naturally have both functional ovarian and testicular tissue to have hormone therapy and/or surgery to align more with the sex traits stereotypical of a single preferred gender.
So-called “true hermaphrodites” do not have functional male and female reproductive systems.
What is a reproductive class?
Woman: Adult Human with XX sex Chromosomes
And anyone that falls outside this binary definition... is neither man nor woman?
Man or woman?
