Often these people are just confused about the names of things, thankfully people this stupid are easy to persuade if you're non confrontational.

Just treat their bizarre claims as an attempt at reasoning, they're trying to start at the part they don't understand rather that the part they do.

It's pretty easy to find a starting point, somthing true of which they are sure. How do we measure the distance from A to B? Could we measure a longer path between them that's not straight, like an arc?
Would there be a difference in those measurements?
So if I am standing here, and you're standing in London, would the distance drawn flat across the map be the same as the distance by plane or boat? If it ain't, either the water the boat is on is curved, the plane can't fly a thousand miles in a straight line. Doesn't matter how far the flat map measure is, whether it's wrong or not. Point is the plane, boat and map would all be the same if the earth were flat.

If they accept the earth is curved, don't push them to the sphere. It's sufficient to prove whoever they've been listening to is a retard.

Bad home area, I deal with at least one of these people a week.
