If you want a real controversial topic, something of a heresy to make women faint and strong men to blanch, you might tackle the idea that sex is anything but "immutable 🙄".

Something I've been beavering away at for some time -- for example, see my recent post on "Binarists vs Spectrumists":

However, that's something of a thread I've picked up and been running with since reading an Aeon article by Paul Griffiths -- university of Sydney, philosophy of science, co-author of Genetics and Philosophy:

Of particular note, the heretical statements to match Galileo's "E pur si muove":

"Many people assume that if there are only two sexes, that means everyone must fall into one of them. But the biological definition of sex doesn’t imply that at all. As well as simultaneous hermaphrodites, which are both male and female, sequential hermaphrodites are first one sex and then the other. There are also individual organisms that are neither male nor female. ....

Nothing in the biological definition of sex requires that every organism be a member of one sex or the other. That might seem surprising, but it follows naturally from defining each sex by the ability to do one thing: to make eggs or to make sperm. Some organisms can do both, while some can’t do either. Consider the sex-switching species described above: what sex are they when they’re halfway through switching?"
