Unpopular opinions are the thoughts of free thinkers who aren't afraid.
"Any man more right than his neighbors constitutes a majority of one already."

No not really, the fallacy is far stronger with the Y.E.Cs than it is with the Flat Earthers.
I say this because I have that amongst the Flat Earthers I have found some that are both open to discussion as to Flat versus Oblate Spheroid and admit quite openly that are NONs ( Non-believers) as well.

This no doubt is true but why post this on an agnostic/atheist site ?. To make ourselves feel superior to those ignorant theists ?.

why is this opinion unpopular?

Well, yeah… everyone knows the Earth is actually hollow and populated by shape-shifting Reptilians who are infiltrating human society at every influential level, including Hollywood entertainment, federal politics, and low-budget community theater. Duh!

So ridiculous that people can believe this total nonsense. Yet, they believe it because someone somewhere is making money off of it through shirts, meetings, and other merchandise.
