I do not expect them to understand science because they do not understand Scripture. The evidence that they do not understand Scripture has nothing to do with the shape of the earth. They do not understand what the Church teaches about exegesis or even what is meant by the literal sense of Scripture. They do not know how much weight to give interpretations from the Fathers. Some of them do not even seem to understand the distinction between canonical and apocryphal writings.
Not only are they wrong about this sort of thing, they will not accept correction when told they are wrong. They are the ones with closed minds, rejecting the actual Catholic approach to Scripture in order to adopt one that better supports their belief in a flat earth. Their posts are full of logical fallacies, appeals to emotion, and name-calling. They show themselves incapable of critical thinking almost every time they write. I have no reason to think they are capable of recognizing a sound science argument when they see one. Their only criterion for accepting an observation or argument is whether it supports flat earth. All of this remains true no matter what shape the earth is.
Jaynek,
You are spot on with that statement : "
I have no reason to think they are capable of recognizing a sound science argument when they see one". They are incapable indeed, and at some point we are going to have to stop trying to make them see, it just won't work. You can push their nose into the facts, and still they will refuse to be corrected. They just start calling you "a troll", because you spoil their fantasies.
Proverbs 29:9: "If a wise man contend with a fool, whether he be angry, or laugh, he shall find no rest."
Can you see how I find it embarrassing that so many Trads reportedly are falling into the flat earth nonsense? It reflects very poorly on all the others and it undermines not only the flat earth nonsense itself, but also all the rest they supposedly stand for, i.e. the Resistance.
If I was moderator here, I would have banned these fools long ago.
In your posts on the other hand I have witnessed far more logic and common sense than I have seen from all the flat earthers put together, and then some. Good on you!
