It certainly makes me wonder why there is any debate at all. Child molesters sometimes photograph the molestation of children. This means they are victimizing innocent people and taking photographs of the victimization. Nazi Germans exterminated Jews and pictures were taken of the result. This seems like a pretty analogous situation to me, but people don't argue that the Jews depicted in holocaust photographs are executed all over again every time somebody looks at one of the pictures. They also don't claim that the demand for holocaust pictures leads to genocide. But if you look at the pictures of children being molested, you are certainly causing them to be molested all over again, and the demand for these pictures is the sole cause of child molestation.
