A lot to agree with, but it is difficult when it makes factually incorrect claims.

Hudson says "It started in the 13th century. The Roman church declared war on other Christian countries, mainly Germany, that didn't accept the Roman Catholic direction for control. And they fought against the orthodox Christian countries. And so they basically hired warlords like William the Conqueror to turn England into a fiefdom."

William the Conqueror - Battle of Hastings, 1066, so hardly the 13th century!
