I was watching this video, and I kept thinking...This may be an artifact of my time in fandom, where love and sex seem to be used to do everything ever, but I really enjoy using the language and imagery of romantic love to discuss something like love for one's country, people, regiment, tribe, etc. That mix of the personal and the political seems to me to be really intensely effective. It catches your attention, because you don't expect it, and it highlights really quickly both a) how much bigger than one person the issue at stake is (since you start with the expectation set up by romance that this is something that really only bares consequences for two-or-so people) and b) how intensely, personally important the issue is (since you're using such evocative language, instead of the drier, more academic language we're used to hearing such issues discussed in).
