The feminist sex wars are sometimes viewed as part of the division that led to the end of the second-wave feminist era and the beginning of third-wave feminism. The debate pitted anti-pornography feminism against sex-positive feminism, and the feminist movement was deeply divided as a result. The sides were characterized by anti-porn and pro-sex groups with disagreements regarding sexuality, sexual representation, pornography, sadomasochism, the role of trans women in the lesbian community, and other sexual issues. The feminist sex wars and lesbian sex wars, or simply the sex wars or porn wars, were acrimonious debates amongst feminists in the late 1970s and early 1980s.
