> the overwhelming majority of "Flat Earthers" are joking, pulling your chain, and refuse to admit it because keeping a straight face is part of the joke for them.
There is little double that some do, but I think you underestimate just how stupid people can be in general. E.g. just using the normal distribution for IQ (mean 100, stddev 15), 9% are below 80.
Now, to be clear: I just want to stretch your imagination. There are tons of people out there who just aren't that bright. Ok fine.
The problem is people who are a nasty combination of low IQ, ignorant, and militant.
Basically, you have people who could be cured of flat Eartherism by going out just one whole night and watching the stars rotate around the pole, just one trip to the ocean with binoculars to watch a ship disappear over the horizon, just one full day of measuring the shadows of the sun and doing trig, yet they refuse and instead sit inside and watch fucking dumbass YouTube videos made by other fucking dumbasses and then will literally get in your face and irate about something they clearly have zero actual direct knowledge of. It really makes you wonder wtf.
But then again, what are you gonna do? I tell them to predict eclipses, but so far no one has taken me up on it.
