    The Purity Myth: How America's Obsession with Virginity Is Hurting Young Women

    The Purity Myth: How America's Obsession with Virginity Is Hurting Young Women by Jessica Valenti PDF, ePub eBook D0wnl0ad

    The United States is obsessed with virginity — from the media to schools to government agencies. In The Purity Myth, Jessica Valenti argues that the country’s intense focus on chastity is damaging to young women. Through in-depth cultural and social analysis, Valenti reveals that powerful messaging on both extremes — ranging from abstinence-only curriculum to "Girls Gone Wild" infomercials — place a young woman's worth entirely on her sexuality. Morals are therefore linked purely to sexual behavior, rather than values like honesty, kindness, and altruism. Valenti sheds light on the value — and hypocrisy — around the notion that girls remain virgins until they’re married by putting into context the historical question of purity, modern abstinence-only education, pornography, and public punishments for those who dare to have sex. The Purity Myth presents a revolutionary argument that girls and women are overly valued for their sexuality, as well as solutions for a future without a damaging emphasis on virginity.
