Philosophical purity is very appealing, but ultimately the justifications we use for why the law is the way it is only have to stand up long enough to convince most interested parties that we're doing the right thing.
When the law is influenced by societal consensus the legal system becomes a farce.
"the Constitution, or any text, should be interpreted [n]either strictly [n]or sloppily; it should be interpreted reasonably"
To criminalize it in all of its forms, is the same thing as criminalizing any sexuality. Perhaps one day we'll create an algorithm that can generate these images without anyone being involved -- does that sound distasteful as well.
At this point even artful depictions of a sexual nature are illegal, criminal offense.
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.
That includes everyone. Women with the most neotenous traits are considered the most attractive in every human society.
