These concerns have been reflected within the feminist motion, with radical feminist teams claiming that pornography was a central underpinning of patriarchy and a direct cause of violence against women. This included feminist BDSM practitioners (notably Samois), prostitutes-rights advocates, and lots of liberal and anti-authoritarian feminists for whom free speech, sexual freedom, and advocacy of girls's company were central considerations. Other feminists identify girls's sexual liberation as the true motive behind the girls's motion. Andrea Dworkin and Robin Morgan began articulating a vehemently anti-porn stance primarily based in radical feminism starting in 1974, and anti-porn feminist groups, resembling Women Against Pornography and related organizations, grew to become extremely lively in various US cities throughout the late 1970s. As anti-porn feminists broadened their criticism and activism to include not only pornography, however prostitution and sadomasochism, other feminists grew to become involved about the direction the motion was taking and grew extra vital of anti-porn feminism. One of many earliest feminist arguments against this anti-pornography pattern amongst feminists was Ellen Willis's essay "Feminism, Moralism, and Pornography" first revealed in October 1979 within the Village Voice.
