People assume that they are the only people with a crazy idea in their heads.
They never hear it from anywhere else. Since there's no way to get together with other people who share or reinforce that view and help you articulate it, you feel like an oddity, an oddball. So you just stay on the side and you don't pay any attention to what's going on. The United States is like the guy at the party who gives cocaine to everybody and still nobody likes him.
