Actually I think there is a geocentrist in the thread presently! I'm not going to give the screen name or ping because I don't recall for sure. Anyway we have had at least one or two show up in these threads. Believe it or not! No flat earthers though. (Yet.)
What is the point of arguing belief? People will believe what they want. If their belief is strong enough, no logic or proof will shake it. In many instances the strength of their belief is viewed as a virtue. This is a good thing or a bad thing, depending on which side of the discussion you’re on.
I can’t remember which, but we have a state public official in Georgia that subscribes to that philosophy.
