When bad people do good things they are generally seen as sinister, as if they are concealing a horrible action behind a facade of good will. So if you believe the government is fundamentally evil, and you see it trying to do something good (which is the whole purpose of FEMA) then its actions are going to look sinister to you. So stories about FEMA having camps (at their core, these are stories about the government using the facade of aid and assistance to hide something evil) will make sense to you because they are consistent with your sentiments about the what the government is. So too would stories about FEMA using disasters as a pretext for land snatching or stories about FEMA ignoring people in peril because these are all stories about an evil government. To the extent that they are consistent with your sentiments about the government, they are easy to accept as true, even if they contradict each other.

Even if you accept the claim that they were duped at face value, what does that say about them? These folk’s whole pretense is that they can “see through the media’s lies” and that they are able to tell what is really going on. But they were not smart enough to recognize that they were part of a propaganda campaign? They want you to believe they have a sophisticated ability to recognize media manipulation but also now want you to believe that they were hapless stooges that were tricked into participating in a media manipulation campaign.
