When it's just tens or hundreds of thousands of people that believe in something ridiculous, we call it delusions but when that number gets into the millions we call it truth. Popularity is indeed the harbinger of truth. In other words, how is this different than the idiots who are convinced terrorists are after them? Just because we haven't yet identified the mental sickness in the latter group doesn't mean their conspiracy theories are true rather than delusions, but we are fine with even going to war to protect them. I see no difference between delusional psychotic patients, in other words, and many run of the mill idiots.
