"Mary is a writer and journalist. After graduating from Oxford University in 2002 with a first-class degree in English Literature, she was an early adopter of millennial precarity, via a twenties spent experimenting with gig economy work, intentional communities, gender nonconformity and unconventional relationship forms.
Along the way she discovered digital culture and web 2.0, co-founding the digital learning marketplace ‘School of Everything’; working as a researcher with the New York-based digital culture think tank ‘The Institute for the Future of the Book’; and curating cult art events.
After the crash of 2008 she worked in marketing while training as a psychotherapist, before discovering marriage, motherhood and small town life - along with an audience as a writer via her political blog."
On 'Reactionary Feminism':
She says: "The central contention of reactionary feminism is that the ideas of 'freedom' and 'progress' themselves are now delivering diminishing returns for all but a shrinking elite. And this is impacting especially severely on women, meaning that in order to remain true to the central task of feminism - advocating for women's political interests - feminists must turn against the theology of progress."
And according to The Conservative Woman: She is Eastern Region Secretary for the Social Democratic Party (SDP).
