We forget that even the English civil Wars were marked by savage battles. More than 200,000 died in England, Wales, Scotland, and Ireland among a population of less than 10,000,000. A recent biographer of Luther has remarked that it would have been better for Europe if Luther had suffered the fate of Hus.
The author probably thinks the Middle Ages were a fun time, also. Maybe he even pines for the public burnings of heretics put on by the Church back then. Afterall, these spectacles were such great entertainment for the ignorant masses, as well as being didactic in nature! What this author reveals about himself is pretty ugly. It sounds to me like an endorsement of the repression formerly practiced by the RC Church. But I have often encountered this same sentiment among Catholics, so I am not surprised by it in the least.
