It’s simply the truth. Go around and ask 20 people if they’ve read a single piece of poetry in the last year, and you’ll see what I’m talking about.
It’s not even being edgy. Most people don’t get high concept art in general, and there’s nothing wrong about it. I certainly don’t understand classical dance, or abstract paintings. You need some degree of competence in any art form to truly appreciate it. To think otherwise is incredibly arrogant.
I don’t think it’s worth it to argue with a person of such worldview. Maybe someone with more patience than me will reply.
