If you want to see a slightly more lighthearted yet ridiculous conspiracist movement... check out the flat-earthers. Yes, it is precisely what it sounds like. These people are real, though harmless as far as I know. Could be wrong. (So. very. paranoid. Though. it's a self parody) But you got to see how deep this rabbit hole goes.
The general consensus is that it started out as people making fun of the concept that grew due to true believers and now it's a mix of the two groups with no way to actually distinguish between the two.
Personally, I'm not that fond or forgiving of conspiracy theorists. It's not just when they piss in my cereal (look at my profile pic), it's when they call up families who had their kids shot telling them they're horrible liars because they're trying to get their guns taken away. "Vicsims," they're called. Or in this case a scientific consensus, which is a big deal, is irrelevant in the face of true knowledge acquired by people explicitly and proudly not a part of the academic process at all who are able to determine the validity of all the relevant case files and how dishonest and wrong everyone else is. Conspiracy theory thinking has real-world effects in the same way that being woefully ill-informed and proud of it inevitably has real-world effects.
All it took for this person to change their point of view was their children being in harm's way. Even then there's not much stopping them from reaping the benefits now and falling back on old habits later which can also affect other people (and given the subject likely will).
