Just going back to the idea of the sex spectrum (which doesn’t actually exist but say for the sake of argument it does); since proponents of this idea are so keen on stressing that sex isn’t just chromosomal but can be hormonal, physical, social etc., how would that actually work…?
Is the tall gay man with a large penis and broad shoulders but low testosterone who likes wearing kilts further along the spectrum than the tall woman with broad shoulders and high testosterone but who likes to present as nonbinary?
What about the trans man who recently transitioned but had two children as a lesbian woman and can’t grow facial hair? Or the woman with a Androgen Insensitivity Syndrome who really likes dresses?
Do you just line them all up like that Mermaids Barbie to G-I-Joe graphic? Or is it more like a plane with four axes, a bit like the graph they used to use at Political Compass to measure where your politics sit?
If I’m a medium woman then can I shift further long the spectrum to extremely woman woman if I try to live more “as” a woman, like add my pronouns to my emails and always wear a dress?
Does getting fat and having menopause shift me back towards the middle? Cos I’m getting chin hairs and my hormones are getting all mixed up. 
If I had to get a double mastectomy (like women I know who have the BRCA genes), is it only top surgery and masculinising if you “identify” that it is?
