The very inwardness of cancel culture creates its moral appeal. The movement becomes more insidious, however, when it marches beyond the borders of nonparticipation and into the realm of prohibition. This has arguably happened in young adult fiction, where social media campaigns can lead to the postponement or even cancellation of a title. That’s a bad result, in part because books themselves, in their infinitely provocative diversity, are a good; but also because the movement is then engaged in trying to make unavailable to everybody else whatever its own members would prefer not to read. History teaches that “No one should have access to the things I hate” is a dangerous claim.
