Dear Ijeawele, or a Feminist Manifesto in Fifteen Suggestions
Автор: Чимаманда Нгози Адичи
Год издания:
A few years ago, Chimamanda Ngozi Adichie received a letter from a dear friend from childhood, asking her how to raise her baby girl as a feminist. Dear Ijeawele is Adichie's letter of response.Here are fifteen invaluable suggestions–compelling, direct, wryly funny, and perceptive–for how to empower a daughter to become a strong, independent woman. From encouraging her to choose a helicopter, and not only a doll, as a toy if she so desires; having open conversations with her about clothes, makeup, and sexuality; debunking the myth that women are somehow biologically arranged to be in the kitchen making dinner, and that men can «allow» women to have full careers, Dear Ijeawele goes right to the heart of sexual politics in the twenty-first century. It will start a new and urgently needed conversation about what it really means to be a woman today.
