How to change people's views, how to change people's view when they really don't wan them to be changed is a subject that greatly interests me. I don't doubt that my methods are very far from perfection, but at times I am sometimes genuinely shocked by how easily people are shocked.
There was a book entitled "The New Psychology of Motivation and Persuasion in Selling", which was written by a couple of PhD's at a Midwestern University some time ago. In it were a couple of rules. One said, "It is not the salesman's job to change a client's beliefs in the course of a sales interview but rather to show them how they benefit despite those beliefs." Perhaps if you start there.
You attempt to persuade (call it what you will) so ask yourself if it really necessary for someone to change a deeply held belief to understand your position. You used the term "Weltanschauung" rather than worldview. I assume that was chosen to assert a more sophisticated, comprehensive and even more hard won view than is implied by the more simple word "worldview". That is how it is usually understood. When considering something so comprehensive and hard won should you be surprised that others do not give it up easily? And given the importance of ones weltanschauung should you be surprised that people may be shocked when you challenge them at such a fundamental level? To those not at play in their minds at the moment some of your ideas are tantamount to asking someone to seriously consider the validity of gravity.
I think you are quite successful at what you set out to do. You set out to shock or at least disturb people and you succeed. Good job. But changing their minds is something quite different.
Sometimes people or even entire societies land on a moral position that is comfortable, workable and safe. These moral positions are at the heart of any workable group of people. Call them shallow if you like but they must appeal to the farm worker and the professor alike. They are not resting points but calls to action. We do not abhor Hitler at some philosophical level but rather he is a rallying point calling us to action against or for certain moral "eaches".
As a man he was actually quite unremarkable, though a good speech maker. He was the odd piece in a complicated jigsaw puzzle that made a pastoral scene into a nightmare. We probably should not give him much thought at all. What happened on his watch is quite another thing altogether. The moral take-away has become really quite simple. He has become the bumper that stops us when we get too close to the edge. So when you get too far into the weeds about him in his time people naturally resist. Understanding history is not what Hitler is about anymore. Understanding morality is.
I am OK with your free speech here on POFO. I find your posts interesting sometimes. But in this case society has put a stake in the political landscape and comparing someone to Hitler, for whatever reason, is to attempt to use him for an unacceptable purpose. Anymore he is just a symbol. Nothing more.
I find Hitler interesting in context and have read several books concerned with him recently. I do not, however, find him as interesting as many of the people around him. I just finished a biography of "Leni" Riefenstahl and was left with a real sense of real people, famous or otherwise, trying to navigate that thing called the Third Reich. It was, for many people, an enormously empowering time. At least for awhile.
Circling back I think that the era of Trump (and I am NOT comparing Trump to Hitler AT ALL) is just like those days in this regard. A not insignificant group of people, who felt left behind by "progress" see this time as empowering in ways they have not experienced and neither have their parents (the boomers). What will history say of Trump? Who knows. I suspect he will be just the masthead of a pivotal time in history. A time when we decide whether "the people" will emerge triumphant over the forces of oppression and greed or whether they will return to their traditional position as rabble stuffed full of bread and entertained by the circus.
