Harry Crouch’s San Diego office is a study in male outrage. The shelves are stacked with books entitled Making Monsters: False Memories, Psychotherapy and Sexual Hysteria, Legalising Misandry and Hotsy Totsy FemiNazi, badges – “California is Sexist & Hateful Against Men” – adorn the walls, and a bumper sticker on the back of the door reads: “Don’t be THAT girl: embarrassed about a hook-up? Angry at a boyfriend? Willing to destroy a life?”
