Deluded. People who are living under the delusion that their work is separate from their identity and experience are generally people who are benefiting from enormous amounts of structural privilege.
Dunham also admits to invoking identity politics in her arts, as she states that it is impossible for an artist to separate their work from their experience in their identity and that artists who reject this statement must be privileged. By privileged I assume she means part of the majority and that an artist of the majority will think they are depicting everyday images but they arei n fact drawing how they perceive the world too. The difference is that an artist of the majority is more likely to depict an image that conforms to the norm while a minority artist will not.Not being preoccupied with their identity because it conforms to the norm and therefore their artwork will as well, a majority artist will think their artwork has nothing to do with their own experience.
