You can't laugh or talk aloud in public, and even your shoes must make no sound. Wearing cosmetics or showing your ankles is punishable by whipping; women have had their fingers amputated for wearing nail polish.You paint the windows of your house black so you cannot be seen from the outside. You are forbidden from walking on your balcony or in your backyard. It has been years since the sun shone on your face. And all public references to you have disappeared.You are a woman in Afghanistan today, living under the regime of the Islamic fundamentalist Taliban.And if you are one of the nearly 2,000 women who belong to The Revolutionary Association of the Women of Afghanistan, or RAWA, you are using the Internet to fight back.
