I get what you are saying, and I agree to a point, but I don’t always agree, as the whims of artists can change.
Example: Steven Spielberg reissued E.T. The Extra-Terrestrial in 2002 with all those nasty guns airbrushed out and a few lines censored, to the general dismay of purists the world over (plus he added some horrible CGI tweaks to the Carlo Rambaldi’s amazing puppetwork). He later admitted this was a mistake (thank goodness) and reissued the original 1982 version.
I actually do believe it is important to preserve the original work of artists, no matter how offensive even they might find it, especially when it is of great cultural significance. I would rather the work appeared as originally shown, with any curated warnings as needed. The same is true with books (for example, Tintin and the Congo has a warning at the start about racist colonial attitudes, and Herge later regarded this volume as “the sins of his youth” but it is important the work remains accessible).
Thank you for reading and commenting. :)
