@Tadano @madonline He blocked me a while back. I was debating flat earth and I tried my best to be logical and not cite any space agency (basically avoiding the appeal-to-authority fallacy). I brought up how even back in the 1800s, railroad construction still took the curvature of the Earth into account. He brought up some flight paths that only make sense on the flat earth map while looking weird on a Cartesian map (the 2D map that most people use), but I showed how they made sense if you draw them on an actual globe.

Yet, he still insisted that I'm the brainwashed one and blocked me.
