Re: Still find it amazing
The trouble is, those flat Earth types will just tell you that your picture is a fake, or possibly it's spherical aberration caused by the camera lens, or {insert pseudo-scientific bullshit here}. There's nothing you could show them that would change their mind.
Twenty years ago the majority of flat Earthers were just trolls (and there's definitely crossover with elReg comentards there), but these days there seems to be more people who actually believe that nonsense.
