Do you have any data to back this up?
My guess is that if you frame it the right way, most people would vote for censoring the Internet
1. Season 4, episode 9 "Numbers"
Well, people are very protective of their email, that's why. Email is the key to a person's online identity and should be guarded like one's wallet or house keys. But wait until the children are brought into the debate. "Of course, everyone knows _you_ are legit, but there are predators creeping around in the seedy underbelly of the internet. These sexual predators will prey on your children through email and social networking sites. We need safeguards in place to ensure that predators are not able to operate freely on the internet and thus ensure your and your family's freedom and security."
Those predator shows on MSNBC where they basically entice some disturbed person with a made up fantasy, parade him in front of the cameras, talk about all the what-ifs and then arrest him only to have him show up on the next episode reinforces this. Aside: It drives me bonkers when the host says, "You came here to meet a 14 year old boy. What would have happened if we were not here?" I'll tell you. Absolutely nothing. Because there was no 14 year old boy in a chat room looking to meet 45 year old child molesters and there was no 14 year old boy waiting for him in the house.
There are smart people- good parents- who will eat that kind of crap up. They are the kind of parents that are involved in their children's lives. They help them with homework and know their friends and their friend's parents. They talk to their children about risks and staying safe. These are the kind of parents who have the least to worry about, but also the ones who will argue most passionately in favor of policies like this.
I'm not sure if it was constructive. However, the parent poster was asking for sources.
But his larger point remains intact: Freedom of the press/Internet is only an axiomatic good in educated America and Europe. It's on shaky ground in the rest of the world, which in a democratic referendum would make the educated population of America and Europe a rounding error.
