Biological sex is a multidimensional variable with various components.
It's not - physical, phenotypical presentation of the body is variable and has various components, but sex is a system of two parts. If a type of human other than male or female existed, it would only not be an anomaly/disorder if it had its own reproductive function. But there are only two sexed functions - to provide sperm or egg.
But again, even if it was "a multidimensional variable with various components", so what? Why are you trying so hard to twist reality, science and agreed definitions to "prove" that sex isn't binary - when it not being binary doesn't advance your argument anyway?
If you're male, you're not female. The binariness or non-binariness of sex doesn't change this, even if they were just two of a hundred sexes. If you think DSDs prove a male can be a female by saying so, why is that? Why doesn't this apply to actual fully non-binary features like height, age and ethnicity? Age is as full and infinite a spectrum as can be, it does actually change, and yet I STILL can't magically be 8 or 80 when I'm 40, and expect to have the rights of people of those ages just because I said so.
Can you answer this?
