I think flat earth ideas are fascinating. Guess I'm a bit nuts but I enjoy reading how they explain things. :)
I don't think they are more dumb than anyone else. If you ask someone random to explain how gravity keeps the water on the surface, they can't of course. Everyone goes to a web page and looks it up.
So I enjoy reading it. It's just fun and interesting.
It's like catching a little kid in a lie and they just keep on making up more and more hilarious crap to cover the initial lie. Each lie builds on itself requiring a bigger, more ridiculous lie to cover it up and before you know it, you went from who ate the missing yogurt to now the sky is a glass dome, the sun is a giant flashlight that the government turns on and off and the moon only glows because of magical glow worms that live on its surface
Haha yeah I can see how it's similar, specially if you have never read about it yourself and someone says "we actually live under a dome", which means everything must be explained another way, since there is no space, no satellites, nothing. :)
