Even if there's no immediate mortal danger, there's still potential danger. Like said person may live on the plains with no intention of going anywhere with a cliff. But they eventually may. Or they could infect others with their belief, like how cults tend to work.

I really don't want anyone to take anything I say at face value. What I want is for people to generally be more logical and think things through on their own, particularly things in which there's at least potential danger. And sad to say I've instead been seeing a lot of kool aid drinking, even around here.
