"Censorship is telling a man he can't have a steak just because a baby can't chew it." - Heinlein

If you hand power to the state every time people fail to properly handle their responsibilities, you end up in a dictatorship. It is a parent's responsibility to keep their kids away from the dark corners of the internet. Thoughtful regulation would create tools to allow them to do that easily, not hand parenting over to governments.
