I’m tempted to say that what we have here is a failure to communicate. That is a line repeatedly used, in a very old movie, by a prison warden of dubious virtue. The word ‘communicate’ stands for the strong god of control.
The problem is that people die for other people to maintain control. But who defines what should be allowed and what suppressed?
This is the not a post 1945 question nor strictly able to be hung on John Steward Mill, or even the European Philosophes of the Enlightenment. It is directly a result of the Scientific Revolution with Copernicus as the titular lead.
But that is just a result of humanity instinctively wishing for a strong person as a symbol. And that is the problem.
What passes for ‘conservative’ or ‘rightist’ thinking is not thinking but longing for a father to whip society into shape. That is, of course, self destructive on a small planet facing complex nonlinear change.
This is a product of the endless stirring of the very cold and nearly empty pot of Western Civilization. There are centuries of history in there but it is not something that needs to be reheated and served again. Where that has been attempted it has caused a very bad case of the shits. Trump in the US illustrates this.
The problem is the desperate quest among people who refuse to look at reality and see that we struggling to extricate ourselves from the shell of the past. This is the equivalent of wiring together the shell that is cracking in the human metamorphosis to new forms (the plural is very intentional) required to survive.
