Out of the huge idea space of possible causally linked events, some of them make good stories and some do not. That doesn't tell you rather it's true or not.

But people only believe things that make sense to them. When it comes to controversial issues, then ya, you'll find that most people will be divided on it. However, we elect people to lead us in the faith that the majority opinion is right. So even that isn't entirly true. And out of the vast majority of possible ideas, most people that live in the same society will agree or disagree the same way on the majority of them, esspecially if they have the same background knowledge.
