I find the whole flat earth thing absolutely fascinating. I mean... it's wonderfully batshit and crazy to have re-emerged into the mainstream modern world. It's so easily disprovable that it requires a huge amount of actual cognitive dissonance to hold that view. An insane amount - the fact anyone can do it and function in the modern world is absolutely amazing as far as I'm concerned. Boo hiss for ruining his fun with things like maths! :o)
