Has homosexuality? In general in many of these cases they is definitely some element of OCD involved, as in hoarding millions of images, and the criminal offenses are set up in a way to penalize for each image using the same sort of logic as above. But then that's common for other people with what are considered normal sexual orientations, having a huge porn collection.

I mean the deviant element of this is that it's all so taboo, I mean after all "think of the children" (tm). We should treat it as any other crime and try to do harm reduction.

There was an episode of radiolab or something where a guy had a brain injury and became an obsessive child porn collector. The DA argued that even if he had an illness, if he was cognizant enough to hide his activity from his spouse, he was cognizant enough to seek help instead of continuing his behavior in secret.
