Your discussion of the seeming contradiction between the violence inherent in chivalry and the seeming unchristian nature of that violence is really interesting--and was a source of enormous debate in the Middle Ages. On the one hand, you have holy war being advocated by various popes and rulers during the crusades, religious orders that are also knightly orders like the Knights Templar, and, at the same time, you have a push for a return to nonviolent, Christ-like lives as seen in religious orders like the friars. I think you're right to note that we're seeming some of the tension bleed over here into the discussions around the beheading game!
