Since Fox News started fact-checking Trump, Trump's followers have stopped treating Fox News as a reliable source and are voting with their feet towards OANN another very far right sources. They're clinging to lies (politely: disinformation) even in the face of evidence to the contrary from a source that they formerly considered reliable.

That is my point.

Conservatives (or, at least, Trump followers) will turn their backs on sources of information that they considered trustworthy if those sources contradict the leader de jour.
