Addendum to #4: If you have been insulted and it's quite justifiable, then if the insulting party does not accept your duel of honor, that person(s) should be aggressively ostracized, ridiculed, and literally have his/her life on Dwilight be so horrible that he/she would wish he/she were dead. I do not like it when people talk big but back out on the natural consequences. At least Bowie for all his talk actually does face the music (and by chance walks away, impressively enough).
Just because someone may insult/offend you doesn't necessarily mean you have to challenge them to duels, though. Indeed, especially for people who know they won't
win those duels, vengeance and honor if often regained through many other means. Often means that turn out much more for the better of both parties and the realm at large, even.
