AKA Flat Earther, they belong to the Flat Brain Society. They think the Earth is flat and that some evil dudes made it a globe. You cannot argue with them, they have bogus logic and get very angry when you prove they are wrong.

I was banned from a flat brainer discord after proving their argument wrong! lmfao
It went like this:
Him: "That lens represents atmospheric refraction"
Me: "Actually, the atmopshere acts more like a wedge lens, not a fresnel lens"

(I don't actually know the correct lens, I was just setting up a trap.)
Him: "How can you prove that it acts as a wedge lens?"
Me: "How can you prove that it acts as a fresnel lens?"
Him: "You are just doing hand-wave dismissals, you are yet to answer my question!"
Me: "Are you kidding me?"
*gets banned*
That guy is a flat brainer, he thinks the earth is flat. No power in this world can make him think otherwise.
