Yeah, I think that RaceFail (the whole thing, not just the Wrede stuff) keeps bumping up against an idea that has not entirely caught on with writers: that there is more than one kind of conversation to have about a book. Some kinds of conversation require that some or all of the book has been read, but some kinds of conversation work equally well given some reasonable summaries and facts passed on from other readers. And that not all "criticism" of a book or its tropes/premise is "criticism" in the academic sense, but it is not automatically invalidated because of that.
