Yes, we can ask each of the article authors to respond to that question within their pieces, but it's too limited and too limiting to make a whole issue about.
The content of the texts is certainly worth analyzing, but if that's all we do, it will leave out how the music functions, how it is different in different settings, how it speaks differently to different individuals, and how it draws people into the issue you want to get them to think about.
You can keep chopping at that one particular tree, sure.
But you'll lose the forest, for certain, if you do.
Because all the rest of the trees will tiptoe silently away and start singing someplace else....
