Remember that it wasn't so long ago that everyone "knew" the world was flat and you were a whackjob if you believed any differently
Ancient Greeks had already calculated the Earth's radius. In medieval Europe, educated people knew the Earth was round.
Columbus did *not* face resistance because people thought the Earth was flat. He faced resistance because people correctly pointed that the Earth was about 40000km in circunference and that his ships could not reach Asia by traveling West. Columbus based his expedition on faulty calculations.
Columbus was lucky that America was in the way.
