>How exactly do they think that parents can ban it?

Like this:

"You're allowed to walk to your friend's house, but don't suddenly sprint out into the street."

Or,

"You're allowed to talk to the librarian, but not the guy who stands around outside with a paper bag in his hands."

Or maybe,

"You're allowed to put things in the microwave, but not metal utensils."
