So true. If one looks closely at actual (as opposed to the false caricature most people hold in their mind) "conspiracy theories", very often they are based on reasonable questions or the desire for more details & study, with a big percentage of actual idiots also participating in the discussion. And when you observe their detractors, say on here or reddit, you will usually see an unfortunate strawman or worst-possible-interpretation approach being taken to claims being discussed.

The human mind is extremely susceptible to various fallacies such as confirmation bias. Usually this is beneficial, but often it can be very harmful.
