There is a multitude of reasons...
1) You reject Flat Earth Theory
I'm an idoit because I don't share you faith? I should be burned for that ?
2) Failing that, you neglected to even read the FAQ
False, I read it all and that why I ask questions (it don't answer them)
3) Failing that, you neglected to lurk moar
I dont know what it's mean (but I tough it better for me)
4) Barring consideration of any of these, you apparently joined these forums with serious intent
Yes. I joined these forums with the intent to know how people, in 2008, could seriously think that earth is flat. Apparently, it is not here that I could learn anything valuable. You act as fanatics; all other's ideas is shit, dont believe them, believe me because I have the holy wisdom ... .
The only answers a get up to now is being blast because I questionne your theory
Well, you certainly are shitty at it.
Bless me and my barbed wit! 
Wow what a great argumentation. It show the solid bases of your theory !!
READ THE FAQ!Anything not answered in the FAQ has probably already been answered on the forums somewhere. You are recommended to search for these previously answered questions rather than waste our time asking them again.
Also, anything not answered in the FAQ probably isn't even worth knowing anyway.
