By the people that come here and think you are actually serious.
The general opinion seems to be there are really only a few serious true flat earth believers.
This website seems to be populated by us "round earthers" but we really do take most of flat earth as pure nonsense.
I could go into more details, but just read the things from FE's to see what I mean.LOL.
But as another RE says, "Shalom and welcome to the trenches."
Let me give you just one example.
I don't know if you have ever been down to a beach on an ocean or have been to sea on a ship and looked out at the horizon on a clear calm day.
But FE says that you won't see the horizon but just an indistinct blur that fades away in the distance.
Hope you have as much fun as some of us "Round Earthers" do.
NASA is aĺl fakes, and along with all the scientists, engineers, etc. are paid "shills" to hide the fact that the earth is flat. Read on !
