My own personal conspiracy theory is that Flat Earthers, Anti-vaxxers and all the other “Facebook boomer” conspiracies are just a strategy to discredit other “more real” conspiracies: if you believe that 9/11 was an inside job you’re bundled with people that believe that Earth is a frisbee and smart people don’t want that so they keep themselves from exploring anything else.
Also aliens fucked apes and that’s how we got here.
