I’m not sure increasing punishment is actually an effective manner of combating this. The social implications of being a child predator are likely to have a more deterrent effect than the penal system imo (I don’t have data to back that).
I, personally, am an advocate for making treatment for pedophiles freely, easily, and safely accessible. I’d much rather help people be productive, non-violent members of society than lock them up, if given a choice.
