To me Populism is the social, political values of the general population for a given country or society. This has historically meant that if you attack the populist ideals of a country you are attacking the social cultural values of that society.
This is why most in America do not comprehend Antifa or the many Corporation supported organizations that are funding such. Something I think is true is that countries that do not have clear social cultural ideas that cement the society together generally don't have populism within there boarders. Thus the boarders are really a wall making the country a prison.
That is a interesing view. Normally "Populists" implant a common enemy. And speaking about Antifa, probably I will make a post about them soon o,o
The truth is if you want to attack people with ill logic, you must attack the terms instead of the logic. That is what I think is happening and why populism is coming back is because those within the boarders of a country wish to keep the culture and tradition intact.
