You must be blissfully unaware of the child-oriented fetishes that exist online. I know kink-shaming is a no-no, but I find it hard to believe that adults who participate in these activities don't have any desire to include real children. Just like I find it hard to believe that someone who uses an "islamic terrorist" target at a gun range doesn't have any desire to shoot a real one.
EDIT: replace "islamic terrorist" with "gangster thug" (I don't like altering comments in this way so just pretend I did)
