Successfully diverted the threat from its original subject, where no flat earth believer dares to commit to a straight answer because obviously, all the people that live between the Tropic of Cancer and the Tropic of Capricorn are in on the conspiracy ... because all of them observe the sun going in a straight line, east to west, during a culmination.
The Tropic of Cancer, by the way, is the most northerly circle of latitude on the Earth at which the Sun appears directly overhead at its culmination. Its southern equivalent is the Tropic of Capricorn.
The areas between those two lines include territories of over 100 counties, including China, India, Indonesia, most African nations, the northern halves of Australia and South-America, Central-America and Mexico. Obviously ALL the people in those countries are part of the world wide conspiracy to promote a round earth, because once a year they can just step out on the street, look up and see that the sun is not behaving like flat earth believers claim it does.
