Thank you. I admit to looking for reassurance that it was reasonable to have different standards for mainstreamed subjects than for marginalized ones. I'll have to think about the differences between drawing elements from mythology and setting a story in an historical time. I would feel very, very, uncomfortable if Alexander had rummaged through the a First People's cultural background to pick up a few names and images for his stories, and for me what is important is something you mentioned in your OP--doing harm and defending it as art. Dickinson might have been offended by Alexander's tactics, but I couldn't believe that he was "hurt." This isn't true for other victims of cultural appropriation.
