as sexual objects, things, or commodities; or (ii) women are presented as sexual objects who enjoy humiliation or pain; or (iii) women are presented as sexual objects experiencing sexual pleasure in rape, incest or other sexual assault; or (iv) women are presented as sexual objects tied up, cut up or mutilated or bruised or physically hurt; or (v) women are presented in postures or positions of sexual submission, servility, or display; or (vi) women's body parts—including but not limited to vaginas, breasts, or buttocks—are exhibited such that women are reduced to those parts; or (vii) women are presented being penetrated by objects or animals; or (viii) women are presented in scenarios of degradation, humiliation, injury, torture, shown as filthy or inferior, bleeding, bruised, or hurt in a context that makes these conditions sexual." Robin Morgan and Catharine MacKinnon suggest that certain types of pornography also contribute to violence against women by eroticizing scenes in which women are dominated, coerced, humiliated or sexually assaulted. Some people opposed to pornography, including MacKinnon, charge that the production of pornography entails physical, psychological, and economic coercion of the women who perform and model in it. Opponents of pornography charge that it presents a distorted image of sexual relations and reinforces sexual myths; it shows women as continually available and willing to engage in sex at any time, with any person, on their terms, responding positively to any requests. MacKinnon writes: Pornography affects people's belief in rape myths. So for example if a woman says "I didn't consent" and people have been viewing pornography, they believe rape myths and believe the woman did consent no matter what she said. That when she said no, she meant yes. When she said she didn't want to, that meant more beer. When she said she would prefer to go home, that means she's a lesbian who needs to be given a good corrective experience. Pornography promotes these rape myths and desensitizes people to violence against women so that you need more violence to become sexually aroused if you're a pornography consumer. This is very well documented. Defenders of pornography and anti-censorship activists (including sex-positive feminists) argue that pornography does not seriously impact a mentally healthy individual, since the viewer can distinguish between fantasy and reality. They contend that men and women are objectified in pornography particularly sadistic or masochistic pornography, in which men are objectified and sexually used
