This link is a good example of how public semiotics is maintained in the USA. Whatever you may think of Napolitano or the linked video segment, his popular show was almost certainly cancelled for his views, which are not mainstream.
I post this not so much for political reasons or to support Napolitano, but rather to illustrate how mass semiotics are manipulated by the corporations that control our news media. This is one aspect of the modern version of the First and Second Noble Truths. Delusion in Buddhism absolutely does not just mean being psychotic or “delusional” in the modern sense of the word, but also being ignorant or fooled by false information, manipulated into believing things that are not true. Modern Buddhists must have a sophisticated sense of where their news comes from and what the bases for their social/cultural beliefs are.
