I can speak with some authority on the issue of Gender and Spectra as an actual *spectroscopist*. As a global leader in spectroscopy – the study of spectra – I can assure you that sex and gender and any combination thereof are indeed a spectrum. Whoaa. Trigger warning!
But what *kind* of spectrum needs to be identified. That is the art and science of spectroscopy.
You can have a lovely rainbow which is now used by all the gender fluidity advocates to represent their “community”. But in a rainbow there are nearly equal amounts of red and green and blue light which makes it look white to our eyes that were evolved to detect this light specifically. Not other colors. So gender is very much NOT like a rainbow in which there are equal amounts of all examples of the form.
Now consider your fluorescent light. It also looks white. But it is comprised of sharp spikes of red and green and blue. Your eye cannot really distinguish the whiteness of light as arising from sharp spikes or a continuous rainbow as forms of spectra. That is due to biology and how the eye works. But a scientific detector can easily distinguish sunlight from fluorescent light. The two are totally different in terms of the distribution of colors.
Human sexuality works like a fluorescent lamp and not like sunlight. There is no rainbow spectrum. We are possibly 90% heterosexual, 9% homosexual, 0.9% bisexual, 0.09 % transexual, 0.009% multisexual. I make up these numbers to illustrate the functional form of the phenomenon. So yes, gender and sex are like a spectrum. But they are *nothing* like the proverbial rainbow the SJW like to invoke.
This is terribly confused, to the point of being wrong. "Transexual" is not a term that belongs on a mutually-exclusive list with "heterosexual", "homosexual", and "bisexual"; the latter three refer to sexual attraction, not to one's own gender perception.
I recommend https://www.realityslaststand.com/p/sex-is-not-a-spectrum for a clearer explanation of the science facts.
Nice analogy! However, the piece (e.g. last paragraph) rather confuses “sex” with “sexuality”. Sexuality is, as you argue, a form of spectrum. That doesn’t show that “sex” (roles in reproduction) is a spectrum.
