Author and journalist Mona Eltahawy's essay "Why Do They Hate Us?" was a searing indictment of a culture of misogyny and outright hatred of women in the Middle East that sparked major controversy when it was published in Foreign Policy magazine in 2012. She expands on that thesis in her book "Headscarves and Hymens: Why the Middle East Needs a Sexual Revolution," arguing that the Arab world desperately needs to end its oppression of women. She joins Piya Chattopadhyay for a feature interview.
