Wikipedia summarises a view of some anti-pornography feminists:
[They] say that consumption of pornography is a cause of rape and other forms of violence against women. Robin Morgan summarizes this idea with her often-quoted statement, "Pornography is the theory, and rape is the practice."
Anti-pornography feminists charge that pornography eroticizes the domination, humiliation, and coercion of women, and reinforces sexual and cultural attitudes that are complicit in rape and sexual harassment. MacKinnon argued that pornography leads to an increase in sexual violence against women through fostering rape myths. Such rape myths include the belief that women really want to be raped and that they mean yes when they say no. Additionally, according to MacKinnon, pornography desensitizes viewers to violence against women, and this leads to a progressive need to see more violence in order to become sexually aroused, an effect she claims is well documented.
Similarly, blogger and essayist Hamza Andreas Tzortis argues that there is evidence that:
Pornography, both violent and non-violent, is a major causal factor for the occurrence of rape in modern society. Although there are multi-causal theories established for the crime of rape, empirical and social research evidence is overwhelming in affirming that pornography is a major facilitating and causal factor.

- 56% of rapists implicated pornography in the commission of their offences,
- 66% of rapists claimed they were incited by pornography,
On the other hand, this article by Michael Castleman in Psychology Today refutes similar claims:
But the evidence clearly shows that from a social welfare perspective, porn causes no measurable harm. In fact, as porn viewing has soared, rates of syphilis, gonorrhea, teen sex, teen births, divorce, and rape have all substantially declined. If Internet porn affects society, oddly enough, it looks beneficial. Perhaps mental health professionals should encourage men to view it.
Is there a scientific consensus to the evidence?
