Well, you won that argument. Not that any of us disagreed with you about the shameful number of people who believed and still believe the false Pythagorean Doctrine of a whirling globe earth.
The Ptolemaic/Aristotelean model that dominated Catholic history had a stationary (not whirling) globe earth. The idea of a moving earth developed much later.
Anyhow, your claim that there were "multitudes" of Catholics opposing globe earth depended on quotes that were actually about heliocentrism. Once we exclude these, we are left with a handful of Church Fathers and (the entirely non-authoritative) Cosmas.
The only good thing about Andrew Dickson White is that he provided quotes and citations of the Fathers of the Church against the globe model condemned by three Popes. AD White tried to make the Fathers look stupid but the quotes themselves are gold.
I suspect that your reliance on White is resposible for your misunderstanding concerning how widespread belief in flat earth was. I have never seen a good argument that it was unanimous or even near unanimous even in the Patristic period and it had basically disappeared after that.
