Sadly, there are those amongst us who are wilfully ignorant of facts.
It's the supreme irony of many such conspiracy theories that they appeal to science and yet refuse to accept the overwhelming positions (pick your topic) of the scientific community. Instead, they'll go with an outlier, often of dubious credentials, with "studies" that haven't been adequately peer reviewed for quality.
Agree with the willfully ignorant comment or, perhaps put differently, they willfully exclude any information that doesn't align with their preconceptions. All attempts to highlight the logistical and scaling challenges of most conspiracy theories are simply ignored, often with a comment that the person pointing out those challenges must be part of the conspiracy. The other response is to declare it "fake news" (Oh, how I HATE that term!).
It's truly frightening.
