Radical feminism
Radical feminism has been criticized for being anti-sex. An example of this is the work of Andrea Dworkin. Andrea Dworkin published a book in 1987 called Intercourse. In the book she wrote about how heterosexual sex and pornography is oppressive to women. It is often thought that Intercourse argues that "all heterosexual sex is rape" even though Andrea Dworkin did not say this. Dworkin wrote two books against pornography, Pornography - Men Possessing Women and Pornography and Civil Rights: A New Day for Women's Equality.
