The poem in question conveys not just accurate history, but also it presents an argument in favor of standing for your neighbors . Even more, it conveys the feeling of loneliness when it comes to be your turn - both another argument for community and just a reminder that actual real humans are involves.

Not bad for a few lines of text... very efficient.

Of course your whole statement is ridiculous - the notion that a poem is the foundation of a belief rather than a good conveyance of it, is so stupid that all you are saying is that you can't come up with a good argument and are reaching for bad, unfunny snark to deflect.
