The glass emporium

The Dunning-Kruger effect is when people who know little assume they have sufficient expertise to opine while those who can say more due to more knowledge tend to stay relatively silent. It's basically how society has always functioned where the more arrogant and brash someone is the more they are listened to. This is Trumpism in spades. 

When I was young I wasn't yet as well versed in how this dynamic played out but today it is crystal clear and it is everywhere. People who know very little pontificate as if they were steeped in knowledge while experts in their field are denigrated and told to be quiet.

Dietrich Bonhoeffer understood, before his death by age 45 at the hands of the Nazis, that stupidity was the biggest scourge on society. True malevolence was comparatively small and could be better contained but stupid people bathed in their own ignorance while speaking with conviction often with an agenda of seeking power over others. It was destruction via willful ignorance; the elephant in the glass emporium if you will. 

Stupidity is having strong opinion with no solid basis behind it.

Our current geopolitical climate demonstrates how stupid people can gain the ear of the population who themselves either aren't educated or have little agendas of their own. They may not be true monsters but they fail to see the big picture of how their actions play on the larger societal domino chain. 

During my three decades plus career I would see highly proficient professionals perform for the client and be respected by their peers while not necessarily advancing within the company food chain. Conversely, there were others who knew how to navigate the politics and play the game very well while being less of a performer. It didn't matter because they had the ear of management who didn't see the shop floor as well as the rest of us.

The reason "Christian nationalism" is so dangerous is that it combines black and white selective Old Testament judgement with politics. This is not the benevolent and empathetic Jesus of the Gospels but instead magical thinking cafeteria-style religion combined with monumental levels of stupidity.
