Try finding some Cathar writings.
While I think it’s entirely fair to say that the medieval period gets a bad rap in terms of equating feudalism to the later god-king aristocracies, it’s not in any way unfair to say the medieval church reacted to heresy with violence. (Generally effective and overwhelming violence; if you’re claiming sole moral authority you can’t really tolerate anyone questioning your position.)
@Soyweiser The Cathars are the heretics being extirpated during the Albigensian Crusade.
