But also note that there is a lot of reasonable debate about this, and there are those who defend the moral permissibility of pornography as a form of commercial exchange in which all parties who participate voluntarily benefit. Note also that communities and subcultures vary quite a bit in attitudes towards pornography. One does have to consider the facts at some point: what is the psychological effect of consuming pornography on its consumers; what is the impact of pornography on those who model or act? What is the impact on social values and the treatment of others? There is surprisingly little consensus regarding these data.
What's the moral problem with pornography? As far as I can understand it, it hinges on the concept of 'objectification', which seems to mean treating someone else as a means to your own ends rather than as an end in themselves. But if I go to the corner shop to buy a pint of milk, aren't I treating the guy behind the counter as a means to my own ends (buying a pint of milk) rather than as an end in himself? Does buying milk have the same ethical status as pornography?
