Ehhhh… Song of the South is a truly problematic IP (and not just to some easily dismissed portion of the population) and the issues surrounding book burning are far more socially, politically, and culturally troubling and significant…
BUT…
After a modern book burning, the book is still available to be read (that does not remotely make it OK, of course). What makes the Splash situation so distressing is that, unlike a protested book or film, it’s a work of art that is now gone. It can never be experienced again. That doesn’t make the removal wrong, but I think it does make it more meaningful then the execs making the decision understand, and it does raise issues of theme park attractions as art that may not have clear, satisfying answers.
