I'm saying it wasn't all the institution. I think a lot of people, ordinary people, bought into the same types of ideas about what art and writing should be. Sure, there was plenty who appreciated it, but I'd put money on there being far more decrying the type of stuff that came out.
If we have trends these days about what's popular, what's funded and published, then in those days the "trend" was to ignore our greats, forcing them out. That couldn't happen purely from the church, the church had to have support from quite a few people.
