Leverage

I think American evangelical Christians are going to destroy the world. They will do it through leverage. Leverage is how a minority exerts oversize influence. 

They are a critical, relatively unified voting bloc in the most powerful country in the world. America assumes a certain level of rationality and responsibility. 

The country belongs to the citizens. Why would they trash it? Evangelicals FEEL disempowered, having lost the battle over segregation. It was their Versailles treaty.

The insult and injury had to be avenged. Watch the vengeance now, slowly but in real time, through their most recent agent, Donald Trump. There are there to destroy.
