But I have a tradition with my son of sending each other links of people in other countries shooting things up with their 50 cal machine guns and the like.
I can't imagine why anyone would think that watching such things constitutes any kind of risk to anyone.
My favorite for-example: one of those old great libertarian thinkers applied libertarian principles to the parent-child relationship and decided that a law that compels a parent to feed a child is an immoral law; parents should be free to let their children starve to death.
A triumph of logic over emotion? I guess, if you're okay with a society that permits parents to let their children starve to death without consequence.
It is not logical to allow a child to starve to death. Using an argument that a law is immoral is more about emotion than logic.
