My guest on this week's Book Club podcast is the writer Victoria Smith, whose new book Hags: The Demonisation of Middle-Aged Women explains why one of the oldest forms of misogyny is seeing a vicious resurgence in our own age. She says some of the worst of it now comes from young women. She tells me why she thinks feminists of each new generation seem destined to forget or reject the lessons learned by the previous one, and why female bodies – and the life experiences which go with them – are something that can't be wished away by postmodern theory.
