the moment someone admits that a drawing is a drawing, rather than a real photo (or even a drawing of a photo) you've essentially won.

regardless of your stance on the matter, conflating fictional 'children' with actual children as a matter of concept is actually a very bad thing. It's irrational to pretend a photo of a child being abused (nonsexual or otherwise) with an actual photographed account of such a thing, and science doesn't support banning them since they don't promote actual child exploitation or abuse.
