If people were easy enough to convince that they had been deceived, then I'd not mind so much. It's the extraordinary lengths people will go to in order to protect the bullshit they acquired with far less scepticism. Genuinely wild leaps of logic, shallowness of reasoning, on-the-face-of-it non-sequiturs, claims offered as great defeaters which require only a single moment of reflection to see through.
This is the problem. The problem is how bullshit conscripts its dupes into this self-degradation and bad faith dialogue with others.
And of course, how there are mechanisms in society (LLMs now one of them) which correlate this self-degrading shallowness of reasoning -- so that all at once an expert is faced with millions of people with half-baked notions and a great desire to preserve them.
