Santa Barbara is grieving after a 22-year-old man killed six college students just after posting a misogynistic video online vowing to take his revenge on women for sexually rejecting him. The massacre prompted an unprecedented reaction online with tens of thousands of women joining together to tell their stories of sexual violence, harassment and intimidation. By Sunday, the hashtag #YesAllWomen had gone viral. In speaking out, women were placing the shooting inside a broader context of misogynist violence that often goes ignored. In her new book, "Men Explain Things to Me," author and historian Rebecca Solnit tackles this issue and many others.
