For 99.9999997% +/- .0000003% of all the people on earth, the actual shape of their genitals is pure trivia.
You are the one whose premise relies on "it matters" as if genitals == sex in the first place. And for that .0000003%, is it that hard to just fucking ask?
You don't see my genitals, you see my gender.
Determining a person's GENDER never involves their genitals. In many cases even determining a person's "sex" cannot rely on actually looking at their genitals. Not even genitals gets you to "sex" as if that's even a useful determination at the level of biology we are discussing
The problem that you can't seem to process is that you have no such natural right, no matter how much you wish you did.
You see gender, not sex.
I don't see "gender" at all. It's a feeling inside someone's head, and neither I nor you have shown any evidence of ESP.
Are you under the impression that a person's "gender" is defined by their clothing choices? Does that mean that a female who likes wearing jeans and t-shirts is a man in your eyes, because you can only see clothing and somehow, magically, you are completely blind to all of the secondary and tertiary sex characteristics of the human species?
And it's not a matter of "natural rights" in any fashion. There's no aspect of "rights" to this at all. It's a matter of being capable of observing the real world, not the imaginary androgynous landscape that you seem to wish existed.
That's your problem right there. You refuse to accept that the thing people show you IS their gender. It's a social mechanism. It's the shape of the way they present themselves to the world. More properly than "male" or "female" my gender is "wizard". Because that's how I advertise. Beard, staff, had, bags, sometimes a leather robe (but not in this weather!).
I perceive a giant cloud of "not my fucking business" around pretty much everyone else everywhere because around me is a giant cloud of "not anyone's and certainly not Emily Lake's fucking business".
When I go into a bar, make eye contact (assuming you know the eye contact I'm talking about), and sidle up to someone I say "hello, I'm ___. Only ever ___. And who might you be?" And they say "_____, (hopefully insert pronouns here)", and then they've successfully invoked a set of cultural expectations on behavior and experience that gives me a general idea of whether I'm going to like where it'll take me.
That is not imaginary. That is real. Now, when someone asks me, "they/them, but I can do masculine pronouns if that's easier for you". That's also not imaginary. I being the one doing the preferring know what is I prefer after all.
You are the one who is imagining it matters. That any of that shit you cling to about insisting on calling people you will never know or talk to let alone be even remotely at risk of seeing so much as a pixel of the genital thereof, by what you assume their genital to be.
I have been through whole conversations with people, had whole relationships while never once clearly identifying them, as they never clearly identify themselves, by any pronouns at all.
Somehow, I manage to live this very real existence where it doesn't have to matter in the way you insist that it does.
It is not that I imagine the landscape to be androgenous, I just don't see any point in genderizing or ascribing genitals to it, and somehow I manage to still live a pretty decent life.
It's not that I see the landscape as androgenous. I just don't come to it with expectations the way you want to. I fear large people with breasts and long hair and dresses who are striking and assaulting smaller people with beards and a decided lack of breasts. I don't see a "man" or "woman" I see "230 lb ape, with arm muscles that swing around 10-15 lb weights all day, and leg muscles that bear 130 lbs of torso minimum", I see "150 lb ape who is quite likely sedentary and from his body language, thinks she's going to beat him worse later if he says no now."
That's the relevant calculus there. The breasts and beard are confounding factors.
I see a landscape of relevancies. The fact is, almost always genitals are not actually relevant to the social reality of a situation. Instead, it's the gender that matters, or even perhaps something not gendered at all depending on the context and it's very laughably easy to withhold assumptions of genitals you don't have permission to touch or see anyway, and easier still to withhold assumptions of gender until they tell you.
