Advocates of the Free Love Movement, including early anarcha-feminists such as Voltairine de Cleyre and Emma Goldman, as well as Victoria Woodhull, Thomas Low Nichols, and Mary Gove Nichols, joined a critique of marital rape to advocate women's autonomy and sexual pleasure. Moses Harman, a Kansas-based publisher and advocate for women's rights, was jailed twice under the Comstock laws for publishing articles (by a woman who was victimized and a doctor who treated marital rape survivors) decrying marital rape. De Cleyre defended Harman in a well-known article, "Sexual Slavery." She refused to draw any distinction between rape outside of and within marriage: "And that is rape, where a man forces himself sexually upon a woman whether he is licensed by the marriage law to do it or not."
