If I'm reading this correctly, Kay is saying that indigenous books are "not the ones we want." It would be interesting to compare the sales of Native writer Thomas King to Kay's sales (or, for that matter, my sales). https://twitter.com/jonkay/status/1073587375647940610 …
He's saying grants are going in inordinate numbers to Native writers, who we're supposed to want but don't really want. The logical inference is that Native's write books that we don't want (otherwise why mention Natives as he did?).
