"All sex, even consensual sex between a married couple, is an act of violence perpetrated against a woman." - Catherine MacKinnon
"Men who are unjustly accused of rape can sometimes gain from the experience." - Catherine Comin
"Men are rapists, batterers, plunderers, killers; these same men are religious prophets, poets, heroes, figures of romance, adventure, accomplishment, figures ennobled by tragedy and defeat. Men have claimed the earth, called it "Her". Men ruin Her. Men have airplanes, guns, bombs, poisonous gases, weapons so perverse and deadly that they defy any authentically human imagination." - Andrea Dworkin
"I claim that rape exists any time sexual intercourse occurs when it has not been initiated by the woman, out of her own genuine affection and desire." - Robin Morgan
"I feel that 'man-hating' is an honorable and viable political act, that the oppressed have a right to class-hatred against the class that is oppressing them." - Robin Morgan
