However, even in this area of interest, the account introduces errors that are sympathetic to the church. For example, the account has a long thread about the construction of cathedrals, which paints a picture of religiously inspired communities pulling together to achieve something extraordinary. One post says that “Most of the labor [to construct a cathedral] was ordinary townsfolk or local craftsmen, carving it all lovingly by hand.” This is not correct; the stonecutters who carried out some of the more advanced work were typically itinerant and went wherever there was paid work.
I agree that religion can inspire communities to come together to build massive projects, but if you're going to make that claim, Cathedrals are probably the worst example when you have things like the Pyramids, Stonehenge and Göbekli Tepe as examples of massive community building projects done because of religion by ordinary townsfolk and local craftspeople. It sounds like they want to make a specific type of Western Christianity be the model when it is not a good one.
And I do mean it when I say a specific type of Western Christianity, because there are even examples they could have used from other Christian communities from the same era which were probably not built by itinerant labour:

I'm no expert on any of this stuff, I just enjoy history and archaeology, so this sort of thing just irritates me.
