Hence we say sex is a spectrum, as humans can and do have hormonal, genetic, chromosomal sex characteristics that don't match their assignment at birth, or their identity. Humans are amazingly diverse.
Ummm no, I don’t think it has been proven that sex is a spectrum. There is plenty of pseudo science theories but no one yet has proven that sex is a spectrum.
You keep bringing people’s medical conditions in as evidence to your beliefs.
People can be reliably sexed using a combination of criteria. But the basic premise that has as reliable today as it was 100.000 years ago is that human sex is binary. It requires a small gamete and a large gamete to produce another human.
There has always been variations of human bodies but always based around the production (whether successfully produced or not) of either small gametes or large gametes. That is what sex is all about.
There are NO third gametes.
And please share what values are then used to place people along the spectrum? Who is more female than another female? What makes this so? What do you call those in the very middle?
Or are there many just variations of a female and a male body?
