You assume people ever cared about facts. People are more emotional than they are rational when it comes to things that are outside of their control. While someone might be perfectly rational and logical in their life (e.g. they pay their taxes, they go to work, they make smart choices in their day to day lives), when it comes to things that are outside of our control (politics, economy, death, etc).

We have always been pretty irrational and easy to manipulate.
