Flat earthers don’t believe in a flat earth. What they actually believe is that Satan is fighting a war for the minds of people, and education is a tool of satan to lead you away from god. All other nonsense they spew stems from that— they don’t believe the earth is flat because evidence shows it, they find evidence to support the earth being flat because the education system, which they believe to be from Satan, tells you it’s spherical.
And most (but not all) flat earthers have moved on to the next conspiracy that supports their central belief (Satan is fighting a war for your mind) and don’t care much about flat earth anymore. Flat earth was never the point, not being swayed by Satan is always the center.


I think your wife’s case was actually significantly different from “flat earthers”, as a community. There’s ignorance, which can be corrected with knowledge and information and reasoning, and there’s willful defiance, which cannot. The very fact that she was freaked out and had a crisis, which enabled facts to enter her head, demonstrates that.
