There is a whole bag full of misogynist issues round "non-binary" waiting to be unpacked, IMO. Round "male bodies = default human" and one rule for the penis people, another for the vulva people.
IMO, Nigella was spot on with the original article.
What we need to ask is why "non-binary" and "androgynous" are always framed as "just being human", where "just being human" seems to be "like a human man"?
Male non-binary - bit of mascara, high heels, dress with a bit of swish. You're good to go.
Female non-binary - lop off perfectly healthy body parts. Then you might be good to go (but we'll still pay you less, because... we know you're actually a vulva person under that shapeless top and shapeless trousers).
Some time in their mid forties I expect all these be-vulvaed non-binary people with double mastectomy scars will realise they've been had.
