That's the point. People who support mass surveillance or encryption bans only do so because they're uninformed (or have been purposely misinformed by others). You teach regular people how it actually works and they change their tune.
On the subject of encryption bans and backdoors, I explained that this would make it easier for them to be the target of hacks and fraud. This concerned them, but ultimately they are under the impression that the people handling it know more than me and I can't be correct.
I don't think they are particularly out-of-the-ordinary, so I don't think the solution is a simple act of informing people. I think people who do care about this stuff largely need to accept the possibility that this isn't important to the majority of the population, and that it never will be (no matter how informed the public is). Instead, we need to continue build the tools and the infrastructure to secure ourselves regardless of policy and legislation.
But when I say the kinds of changes being proposed would fundamentally undermine the security encryption provides, they think I'm wrong. Like most of the current presidential-hopefuls, they believe in a magic-bullet that will give the government access but no one else. They think someone smarter than me will implement it, and that my concerns are misplaced.
Again, I don't see this as a strange viewpoint. I think, to some degree, it's what most people believe.
