Radical feminism
In the 1980s the Feminist Sex Wars happened. The Feminist Sex Wars were fights between radical feminists who said that porn, sex work, and BDSM are bad, and sex positive liberal feminists, who said that those things can be feminist. Radical feminism is associated with the second wave of feminism. This ended in the 1990s. Since then radical feminism has been less popular. The third wave of feminism is liberal. Some of the women who started radical feminism have died. However, radical feminism still has influence. In 2012 a book by Julia Long, Anti-Porn: The Resurgence of Anti-Pornography Feminism was published.
