I think flat earth’s comeback is actually a good thing and YouTube is making a mistake. It’s true that nobody 30 years ago believed the earth was flat but they probably couldn’t articulate why they believed that. People who are brave enough today to re-examine their beliefs should be admired, not ridiculed.
Of course flat earthers are wrong, but the coolest part of the documentary is when members of the movement start spending thousands of dollars to conduct experiments to prove their theory. At the end one of them gets a contradictory result to what he expected, and you can see the doubt start to form in his eyes as he smiles and just says something like “Oh, that’s interesting, that’s very interesting.”
YouTube has given nonconformists a platform where they can be honest and be themselves, and it’s unfortunate they look to be trying to take that away. Of course some people on there will hold views that are frankly stupid, but I’d say it’s better than having everyone believing the same thing out of a sense of conformity.
