Or it would make you Olympic runner Caster Semenya. Unlikely however doesn't mean non existent. The fact that the intersexed make up a tiny minority of the population doesn't mean you can just dismiss them as if they don't exist. People seem to have a misunderstanding of what biology is. There are the molecules, proteins, hormones and chemical reactions that comprise life and then there's the terminology we use to catalogue and group these observations into categories and lists that have contextual meaning. Nature itself doesn't care what we call someone with XX chromosones compared to someone with XY chromosones. It doesn't decide that only people with XX chromosones, a vagina, a uterus and ova is a female and nothing else. What about people with XX chromosones, a vagina but no womb? A percentage of females (non intersexed) are born without wombs. About 1 in 5,000. Do they not to get to be real women? Chemical reactions are one thing but the naratives we form around these reactions is less objective science and more subjective sociology.
