Also, CP has a highly limited audience.

This is where I realized that you were talking through your hat. No one really knows what the fan-base for things like CP is like, because of the social and legal stigma attached to it. We know what SOME of the audience looks like, specifically the stupid members of the audience, because they end up getting arrested occasionally.

I think it is quite a stretch to say that you re-injure the person in the photograph by looking at it. How could looking at something produce a victim? While some vague, insufficiently substantiated arguments exist for the notion that it "increases demand" (as if modern CP were being created and sold, instead of created by fathers and sex tourists and freely distributed) they are simply "hollow" (dunno about vile, not placing value judgments here) when applied to CP.
