Many people wonder what Trump tapped into to entice nearly half of the people to his version of populism. It is not merely fascism or his big lie. IT IS WHAT PEOPLE LEARNED AS CHILDREN. For years people learned how to suppress their early teachings that were offensive in society but carried those feelings deep inside. Once legitimized those early lessons surface.
All it took was a bigot like Trump with the veneer of financial success and shared hatreds from an early age.

Donald's dad was sympathetic to the KKK and Donald absorbed all those teachings early.

Childish beliefs lead to childish behavior. It is not that hard to understand Trumpism and its fallacies from this POV. Perhaps this has been said before but we should bear in mind we are dealing with children with real guns.
