I was going to start a thread on this topic, but I think it fits well under pride, so I'll just talk about it here.
Patriotism-
pride for one's country. Patriotism is on many levels, the same way pride is, there's a good side to pride, and a bad side. I think it's good to be proud of one's country, that can definately be a good thing, but many country's (especially WW1 and WW2) have gone to war because of patriotism. Thinking their country was the mightier then everyone else, leading to the arm's race, and mass build up of guns, weapons...etc. Patriotism is another trait the Boromir seems to represent, as he's always talking about the "Men of Minas Tirith," and the "Men from my country."
