Perhaps the folowing list I composed a while back under the pseudonym of 'Lord Byron' will help you get a bearing:

none of them on the list believe the world is flat. this is pretty obvious.
if they are 1) very smart, they don't believe it yet perpetuate the belief as sort of performance art
You are trying to tell me that I don't believe the Earth is flat. Well, you're wrong. I decide what I believe and not anyone else, and I believe the Earth is flat.
Moreover, I have believed this well over a decade now, and I have a bookshelf of literature on it.
And not everyone holds your ignorant opinion. For example, Diego Draw has been around long enough to see that bullhorn is sincere.
How long have you been around?
I tell you what you believe. You don't believe the earth is flat. Everybody does, in fact, hold this opinion, and I dare you to prove otherwise.
