There is nothing nationalistic in my comment above.

I see your point, but I'm using the word loosely to refer to internet flamewars about nations. One could also mention the site guideline about ideological battle. Either way, this kind of flamewar comment isn't what we're looking for here, not least because it tends to evoke worse than others (although it didn't do so in this particular case).
