It is my experience that there are 3 types of flat earthers.
1) Inbred hicks. Isolated from main society, left to their own devices, have less teeth than fingers. They aren't very much use to us.
2) Middle-class illuminati (you guys).
3) Islamic and Christian fundamentalists.
3) is becoming a little bit of a problem. We find ourselves in the company of religious crackpots whose justification for a flat earth is 'god said so'. Which is a bit upsetting when we try so hard to ascertain the science behind earth's shape. They aren't really a political entity we want to associate with.
But anyway, they are there. Below is one such individual.
Can we take anything from their research?
