This scares me too. So many people seem to be eager to believe that the people around them are one dimensional cartoon villains.
It seems like some people have a lot of trouble with uncertainty. They have a need to decisively put things in a nice well defined box, even when there isn't sufficient evidence to do so. I think they might just be unable to say, "you know what, I'm not sure". It's much easier to say " well the news said xyz with their big flashy headlines, so that must be true. Shun the nonbelievers!"
