Sometimes contrarians are right about things. But when they are they bring receipts. They have evidence, repeatable experiments, falsifiable hypotheses, and general academic rigor.
Flat Earthers aren't intimidating to anyone. They're tiring. Like all good conspiracy theories Flat Earth conspiracy theories are unfalsifiable. The Flat Earthers' lack of evidence is defended by them as evidence of some sort of orthodox conspiracy. Evidence contrary to their stupid ideas, including empirical observations, are also just labeled as some orthodox conspiracy.
It's not edgy, funny, or even interesting. It's just fucking stupid. It's a handful of bad faith trolls and a lot of scientifically illiterate boobs that decided to wrap their identities around Internet memes.
