Anyone who believes in a flat earth in 2012, heck even 1812 or 1612, is an idiot who dogmatically clings to a super-ultra-convoluted set of rationalizations and ret-cons that violate Occam's Razor a thousand times over by postulating worldwide conspiracies on a staggering level, so deep that we ought to signs of it everywhere, while providing absolutely no objectively verifiable evidence that has been peer-reviewed that could differentiate their magical scheme of things from the reality of a round earth.
Every possible version of a flat earth map fails, because well, you simply can't do a perfect projection of shape, distance, and continuity of a sphere onto a 2D image. If the earth were flat, we should have a perfect 2D map that has absolutely no troubles of projection at all, such as the Mercator projection, etc., but instead an image which perfectly preserves the features of the earth and is basically an exact miniature replica of the earth. Yet after hundreds or thousands of years of people traveling around the globe diligently making maps as accurately as they possibly can, not a single 2D map has been produced that has been perfectly shaped in all aspects. I wonder why that is..
