People are “consistently inconsistent” in reasoning about controversial topics
I lolled at the qualification of the conspiratorial bent arguments as fallacious. They clearly are not. Conspiracies happen and can take a long time to unwind. They should not make up the bulk of your argument and should not fuel a  position without doubt, but they are not fallacious. Scientist make mistakes, take unwarranted positions and take bribes all the time. (I mean this across all fields not as any kind of direct accusation.) Some scepsis with any consensus is just smart logic.
