There are Americans who believe the moon landing was faked. So much for nationalism. I think it's just something people come up with because they want a way to fight the status quo and can't come up with anything factual (despite plenty of evidence the status quo is wrong about a lot of things), so they just make stuff up. The moon landing was faked is a good thing to make up because you're likely not arguing with anyone who actually did it. You can feel superior while you sound like an idiot.
