It's demon-think, just like a witch hunt. You're on the demon's side, and thus all you say and show are lies and should be dismissed as such, you're manipulated by the demon, and thus all you say and show are the demon's lies and you need to be corrected or intimidated away from them, or you see the truth and agree with the accusations.
Only for witch hunts, the imbalance of power is against the witch; in this case, the illusory demons have so much power against the conspiracy theorists, that they feel helpless and might as well just go about life.
