Christian forum viewing can be quite a worthy endeavor, in my experience.
Reading opinions, beliefs, and worldviews from the 14th Century by those still acting as spokespeople for these things is (somewhat) directly viewing the abysmal ignorance and misplaced certainty mankind was laboring under at the time.
Imagine the paucity of opportunities future mankind will have to experience such a thing - in the unlikely case civilization should outlive the intrinsic and massively intolerant hostility religions have for one another and those who don’t believe.
