Just part of the Nanny State, isn't it? Once you give others the power, they automatically get authority over what you're old enough (or smart/strong enough) to see, and what you are not. Trouble is, most people aren't even aware of this censorship. They simply assume they're being fed the right version of the news. Of reality.
I was just talking about this the other day with a friend. This video from a local news agency had gone viral, and she was raving about it. I dared point out that said agency might not have people's best interests at heart, and that she ought to take everything with a grain of salt. She looked at me like I was a conspiracy theorist, because... why would anyone want to lie?
