This is all interesting discussion. If anyone read my first reply to this you know what has colored my perspective on porn.

I agree with Alex on a lot of this, and I'm honestly surprised that people would defend some of more sick fantasies in porn (sex with step daughter, rape). I don't think that porn would "make" someone rape or have sex with their step daughter, but I certainly think that it would help reinforce that these things are okay in an already sick mind. Watched repeatedly it would make these things seem normal.

I do think that porn is very harmful to the actors that participate in the activity. It makes sense that a lot were abused as children because those of us that were abused almost get the stamp on the forehead that makes others want to abuse us. It’s almost the same way children who are sexually abused are often abused by more than one person and then end up in an abusive relationship. One could say that porn is that abusive relationship.

As far as rape fantasies shown in porn I don't see how it is considered not to be sick to get your rocks off on an watching an illegal activity. If someone watched child porn and got off on that wouldn't you feel this person was sick even if he never had sex with a child? Would you leave your child with the person who watched child porn? Would you want your daughter or sister with a man who got off on watching rape and torture? I know I wouldn't. In the same way I would also be very worried about my daughter if she had rape fantasies. I would wonder what happened to her to make her have those feelings.
