In that there are a lot of crazy ideas about it. For example, I still recall Thomas Schlidt several years ago lamenting at the "millions" of people wiped out by the Church during "that time", as though there is one monolithic entry here.
I was hoping Barney would provide some of his own views about it. Does he think the Church was actually burning people at the stake? What does he think the proceedings were like to determine heresy? What does he think the Pope's role was? And so forth.
