Ummm, any kid heading off to college is allowed to say no. What the world doesn't need is cops and judges deciding mundane issues like what apps he/she has on their phone and sending parents to jail for disagreeing.

What else can we make illegal? How about a parent requiring their kid to eat broccoli. How about demanding the kid maintain a C-average before joining a sports team. Let's also make it illegal for a parent to ask the kid to do some basic chores before playing video games. Surely you have some more ideas while we're at it...
