I don't know from where, and from whom, the impetus for this current example came (and I know nothing about those to whose words links have been provided, other than Rowling herself), I am wary of casting aspersions here. However, I have to suspect that many instances have less to do with the issue (any issue), and more to do with boosting the public profile of the person raising the instance. In such cases, complaining about a book full of the most egregious nonsense written by a nobody would simply be a waste of time. But reading (perhaps through gross misrepresentation) something into the words of someone who's very famous...?if I'd wanted to raise the issue of cultural appropriation
