Most people believe what they want to believe.
The internet allows these people to get together and become a loud vocal group.
So a lot of misinformation is sent from these people, causing confusion on the people who may be neutral on the topic.
So if the person is unable to judge the quality of the information they probably don't trust the internet as it gives them so much stuff that is hard to figure out what is true.
Then you have reports about Spying, Identity Theft and a bunch of other stuff, that is greatly over emphasized so people feel even scared of it.
The people who know how to use the technology knows how to be "Internet Street Smart" However those who struggle are not. And get themselves into more trouble.
The people in your circle they don't trust the internet, like how someone doesn't trust walking in the city. They know not to keep their wallet in their back pocket, dress down... However they are not so worried about a random shooter on a good block.
