The real danger of the Internet is seduction of the arrogantly ignorant. There are far more people who love and respect children than there are those who prey upon them. The ultimate fascism is child abuse. Its victims are Prisoners of War without a Geneva Convention to protect them, hostages to terrorism. Emotional abuse of children can lead, in adulthood, to addiction, rage, a severely damaged sense of self and an inability to truly bond with others.
Child protection is crime prevention.
We cannot have one without the other. There are individuals who are so toxic that their presence threatens us all. They self-identify by their conduct. When it comes to the sexual sadist, psychiatric diagnoses won't protect us. Appeasement endangers us.
