I have to laugh because "sheep" is a shibboleth for crazy beliefs. It's the go-to derogation for people who believe that the earth is flat, that the Apollo Program was faked, that their political adversaries are Satanists who drink the blood of children, and that the word is controlled by shape-shifting alien reptiles.
That's what it's really all about, isn't it? It's about a need to declare your superiority to others. Everyone else is a sheep - but not you. You're smarter, healthier, and better informed than almost everyone - especially about preservatives.
I've seen it said that this is the motivation for conspiracy theories in general. They know a secret. They know how the world really works. This puts them on a level above all of the people who aren't in the know.
Although, I've also seen fear described as a motivator for conspiracy theories like the JFK assassination. If the most protected person in the world can be murdered by a random person, there's no hope for ordinary people, and you could be killed at any moment. If he was the victim of a massive conspiracy, ordinary people aren't important enough to rate that much effort and you can rest easier.
