Is there a Wikipedia page that "some" Americans don't think is a conspiracy? Conspiracies used to be about aliens and secret research programs in bunkers. Now they are about pizza restaurants. I gave a presentation at an Airforce base where a flat-earther accused me of participating in the conspiracy. I wanted to throw him out as a dangerous or unstable person, or strap him to the underside of a plane and show him the curve in person. These days, every article, every statement, has to address the 5-10% of people who just don't believe anything anyone tells them.
I am waiting for one of the "airplanes run on compress air" conspiracy people. (It's the latest version of chemtrails.) We'll have them fill a few aircraft by hand... with buckets.
