What's in a Nation, Bob?

Everyone be sure to wish Big Bad Bob a hip happy birthday in your heart of hearts (it's actually not til September apparently, but don't worry about all that).Somehow the lads this week found their meandering way from welsh identity and Colter's hypothesis on how the Welsh learned the alphabet, to theBretons' place in French society. All the way to asking the big question, what exactly makes these geographical areas, nations? Is national identity inherently bad or good? How do you balance healthy pride in a nation with acceptance of others?
