I couldn't imagine this as metal, with the possible exception of thrash metal. It's a lot for a metal singer to get their vocal chords around, given their style. Both for the sake of the meter and its universality, I'd recommend changing 'push it on the American people' to 'push it on to the people.' Not onto, but on to. It's harder-hitting and the alliteration makes it linger longer in the listener's...
lobes? (I'm bad with alliteration
)
The opening couplet of the chorus felt a little contrived (I think that's how it's done). Remember it doesn't need to be a precise rhyme, and often in metal it doesn't need to be a rhyme at all.
'Every interaction is a debate' would work better as 'every interaction is debate.' You want to keep that pace going, and to avoid scuppering the emotion you've build up, or the vocalist's sense of the beat. Again, with the close of that verse 'so we instead are billed' would work better. Not only for the reasons already mentioned, but it also draws allusions to 'we the people' and similar slogans. Perhaps 'we the people are billed' if you want to really be explicit.
On the whole, I liked the song. It's a novel idea, knocking both romance and flags - two of the most overrated concepts in the history of the world - on their heads. Only, it feels incomplete...instead of your somewhat anti-climactic bridge (its demand to 'make amends' - how can the two houses do that if they're
meant to be opposed? - altered the message of the song), why don't you explain what Juliet's doing in all this? Who represents her? If this is an extended Rome and Juliet metaphor, I feel she needs to be there. The lack of her takes something from the completeness of the metaphor, and thus, the song.
