Andrea Dworkin and Catharine MacKinnon have had great influence on advancement of the theory that sexually explicit expression, or pornography, should be regulated because it differentially harms women. Especially, the Canadian Supreme Court adopted the Dworkin-MacKinnon theory. It decided that obcenity statute in the Criminal Code of Canada did not violate Canadian constitutional free expression guarantee because the portrayal of persons being subjected to degrading or dehumanizing sexual treatment resulted in harm, particularly to women. On the other hand, Anti-censorship Feminist objected that free expression would contributed to promotion of women's equality in society, and restrictions on sexually explicit expression would do more harm than good. I consider these controversies.
