You misspelled debunked as "explained" - biological sex is binary, homo sapiens produces two types of gametes and not a spectrum of them, and is a sexually dimorphic species and not a sexually infinity-morphic species. The power of ideology to make people deny simple observable facts is astounding.
I
am willing to believe that “not willing to accept it” is different from “debunked.”
Humans do produce two types of gametes. Big deal; that does not make sexual development binary. It’s not that simple. Cis-males typically get both kinds, an X and an Y, so they already are a mix. Cis-females get two X’s but they go through a lot of trouble to avoid gene dosage effects by turning off one of the two pairs of genes on the duplicated X’s so they don’t express double the X gene products. There may be two kinds of sperm but the actions they produce on sexual development are far from two binary effects.
And I know there have been discussions of Y only, XXY, androgen insensitivity, etc. people upthread that have been dismissed as too rare to worry about. Why rarity matters in this conversation I don’t know.
But more so how can one look at the range of phenotypes produced even by XY and XX humans and say sex is binary? I probably look a lot more like many women than I look like the young Arnold Schwarzenegger and I know I have an XY karyotype. Conversely I know a lot of very masculine looking XX women. Sex hormone levels are not exclusively binary. There are XX women who naturally make more testosterone than many XY men and vis versa for estrogen. There are pictures in biology books that demonstrate a continuum of genital structures ranging from “fully” male to fully “female” and at no one stage one can say, “okay this is no longer male genitalia and now is female.” Same about breasts. Or faces. Or...
But to move away from biology to psychology: why should it matter so intensely to you or to any one? It is relevant if you intend to have children with someone else. It might be relevant, depending on your open mindedness, if you intended to have sex with someone. But if you think about it the sex you believe yourself to be is rooted in your brain, not your genitals. That is what is crucial to us and how we identify, and biologically the brain and genitalia don’t always match perfectly.
If someone feels they are female what the hell business is it for me to question them in most circumstances? I mentioned there are some issues that can come up which I will discuss, but fundamentally they know better than I who they are. They deserve to be addressed and treated in the fashion they request. Am I to question that on the basis of the angular nature of their face? To demand they strip so I can measure the length of a sexual organ? Ask for a blood draw to run a karyotype? It is none of my business in most situations!
Finally we in our society often seem obsessed with sex/gender. It’s one of the first traits we ask when a baby is born. We look at a stranger and mentally assign them as male or female. But if you think about it, how does it matter so much? What if it isn’t that important to the person themselves? Is that going to be the end of civilization?
