Here's the gist of the argument. Porn influences people's behaviors. That is why almost all sexual predators say they act out things they see in porn. Porn does not CAUSE sexual crimes. Porn is an INFLUENCE in sexual crimes.
An example: Russian kiddie porn is big now. So the porn industry is encouraging people to raid orphanages and get girls to join the porn industry. I know a girl adopted from a Russian orphanage and several of her friends have disappeared into the industry. The porn industry is driving that criminal behavior.
Another example: date rape pics. You drug a girl, take pics/videos of her in various stages of undress and they get added to porn sites. We had several cases here at the college where this happened. The perpertrators say they got this idea from ..TADA.. porn sites.
