As a philosophy professor of 28 years' standing, I was delighted when Oxford University Press (OUP), arguably the world's most prestigious academic publishing house, enthusiastically accepted my proposal in 2020 for a book on the philosophy of sex and gender: Trouble With Gender — Sex Facts, Gender Fictions.
I wanted to probe some of the great quandaries of our time: 'What is gender?', 'What is a woman?', 'Is sex binary?', 'What is gender identity?', 'Why do some people transition from man to woman, or vice versa?' But if I thought that this prestigious publisher was brave enough to pursue difficult subjects in the spirit of free intellectual inquiry, I was mistaken.
In the end, OUP simply couldn't countenance my inescapable but heretical conclusion in the book — that women are adult human females.

Not sure its a book I would ever read, but makes you wonder how many others have not been published and decided that it is best to not make a fuss, and never reveal that they too had had heretical thoughts!
