Yes, I created it some 4 years ago for Twitter discussions on sex in humans. That it is more or less is specific to them hardly precludes its applicability to other species - many farm animals are neutered. But, being based on human demographics, the size of the pies would most likely change accordingly.That silly pie chart. Is it only meant to refer to human beings? I thought you were the one who didn't want to confine the discussion only to mammals.
It doesn't seem logical as regards a vasectomy. Don't they know vasectomies are reversible? Even if you reject the rather obvious point that men still produce sperm if they have been vasectomised, your belated recognition of the present habitual would suggest that a vasectomised man is still male if he gets the vasectomy reversed. What's the difference between a vasectomy and habitual condom use anyway?
You seem to have the idea that membership in categories is "immutable", once in one, in it forever. Were you a teenager at some point? Did you survive the transition out of that category without too much untoward "trauma"?
If a guy with a vasectomy gets it reversed then he's changed his state from sexless to male. As for "habitual condom use", male then not-male then male then not .... Like being "hungry" at breakfast, full shortly thereafter, hungry before lunch, full thereafter, etc., etc., etc.
Y'all seem to be making rather too much of categories and the names for them - turning them into identities - while losing sight of the often quite tangible though often transitory traits that are the "membership dues". Straining at the gnat while swallowing the camel whole.
For the purposes of that graph, what more should I have known? Other than that the biological definitions stipulate that to have a sex is to have functional gonads - which habitually produce sperm or ova for reproduction - of either of two types? And that those with neither are thereby sexLESS?There are all sorts of edge cases implied by that chart but not addressed. It seems to have been put together by someone who knows little of human reproductive biology and nothing of the reproductive biology of other species, even other mammalian species. No serious biologist or medical researcher or practitioner would produce something like that.
