What is the goal of the Flat earthers (the one who believes that the earth is flat)?

Unsure because people have different intentions.

Explanation:

Flat Earthers usually are trolls for attention. They will speak up in order to get any feedback, especially if it’s negative. Most people like this are the ones that said there is no science behind a round earth instead of flat, which has been disproven. Another theory can be that they genuinely believe this, and that they spend time thinking the earth is flat. This opinion can come from wanting to be different or reading/seeing flat earth theories on media.

classical republicanism, also known as civic humanism, is a form of republicanism  developed in the renaissance inspired by the governmental forms and writings of  classical  antiquity, especially such  classical  writers as aristotle, polybius, and cicero.
