May need to listen again but it seemed less like they were saying art can't or isn't supposed to change/shape minds or opinions and it was more that because so many people have had their minds and opinions shaped by art, and because culture has totally supplanted politics, they have difficulty reconciling the idea that people can watch and correctly interpret a piece of art without forming that same attachment or experience with it. Hence: (paraphrasing)"Yes, Obama watched and liked the Boys and interprets it in the same way you did...and no it did not magically spur him to turn over a new leaf and reject his imperialist legacy. That's not how it works. Grow up."
