Seriously, sure, this isn't like a maths problem. But we can have reasoned opinions about art, just as we can have reasoned opinions about whether, say, a piece of software is well or badly written, given that it does what it's technically supposed to. I'm not just saying it's bad because it gave me a nasty feeling in my tummy.

In particular, poetry and art contain ideas. They express ideas powerfully and viscerally. It matters whether we have good or bad ideas, thinking or hot air, new understanding or stale clichés. In this sense, art isn't just like a bag of cheetos. It has consequences. That's why dictatorships have often censored good art, and supported bad art. Good art can express new thoughts. I think the US will need a lot of new thoughts in the next four years.
