The claim that "sex is a spectrum" annoys me.
If it's a spectrum, there needs to be a variable I can measure that sits on a continuous value range. Say from 0 to 500, where 0 is the male end of the spectrum and 500 the female end, or something like that.
So what are the two ends of the value range, and how are they measured?
How do I measure someone's "sex value" on this spectrum?
Also, it implies that some men are "more male" than others and some women are "more female" than others. What does that remind you of?
