One of the striking features of the Dr Seuss fuss is that most commentators seem to be treating this as something new. No one I’ve read in US commentary on the topic seems to be aware that “Dr Seuss, cancelled” is a shot-for-shot remake of a British drama.
It reminded me immediately of the arguments about golliwogs in Enid Blyton’s Noddy books, which started just about the time (a long, long time ago) I grew out of those books, and moved on to reading such gems as the Famous Five . After a long series of adjustments, turning golliwogs into goblins and so on, the issue was resolved by the reissue, in 2009, of a new canonical series, with no golliwogs. (There’s still controversy about golliwogs in general, but not wrt Noddy).
As is always the case, once you know what to look for, you can always find someone who’s made the same point before. In my case, very close to home. Here’s Kate Cantrell and Sharon Bickle from the University of Southern Queensland making exactly this point, with many more examples.
