“In the spread of gender-identity ideology, developments in academia played a crucial role. This is not the place for an extended critique of the thinking that evolved on American campuses out of the 1960s French philosophy and literary criticism into gender studies, queer theory, critical race theory and the like. I will merely focus on what some have dubbed 'applied postmodernism' and the form of activism, known as 'social justice', that seeks to remake humanity along ideological lines. And I will lay out the key elements that have enable transsexuality, once understood as a rare anomaly, to be converted into an all-encompassing theory of sex and gender, and body and mind.

Within applied postmodernism, objectivity is essentially impossible. Logic and reason are not ideals to be striven for, but attempts to shore up privilege. Language is taken to shape reality, not describe it. Oppression is brought into existence by discourse. Equality is no longer achieved by replacing unjust laws and practices with new ones that give everyone the chance to thrive, but by individuals defining their own identities, and 'troubling' or 'queering' the definitions of oppressed groups.

A dualistic ideology can easily be accommodated within such a framework. Being a man or woman – or indeed non-binary or gender-fluid - becomes a matter of finding your own gender identity and revealing it to the world by the medium of preferred pronouns. It is a feeble form of dualism to be sure: the grandeur of Descartes' 'I think, therefore I am' replaced by 'they/them' on a pronoun badge.”
