A form of Digitalsplaining where the perpetrator dismisses any argument by comparing it to Flat Earth belief—a culturally accepted symbol of irrationality. The flatsplainer says “this is literally the Flat Earth of X” or “you sound like a Flat Earther,” regardless of whether the comparison is apt. The goal is to trigger an emotional association that bypasses rational engagement. By equating the target’s position with a universally ridiculed belief, the flatsplainer makes any further discussion seem absurd.
