Flat Earth Society and eccentrics

The Flat Earth Society exists. (http://theflatearthsociety.org/cms/) They think the Earth is a flat disc, not a globe. I guess the globe I have on my bookshelf, with its roundness, would be disturbing to them. Do they have a flat "globe"? It would be easier to stack. I'm fascinated by people like this, and the other people who think the Earth is hollow. (http://www.ourhollowearth.com/). I try not to be unfair, but these people are living a fantasy life. OK, in a sense we all are, but this one is contradicted by facts. Nevertheless, it is fascinating reading, rich with imagination and discovery. The things they say to convince themselves what they believe is true...I won't quote what they say here, it's too involved, but you can get lost in such esoterica. I wouldn't make these people disappear if I could. Society needs eccentricities.
