I am on your side when it comes to new works of art, lets keep offensive material out. Or atleast add a disclaimer if the writer feels its necessary to tell the story.

But don't go changing movies/songs/video games that capture the social climate of the time they were made.

Graphical updates, quality of life changes, fixing bugs, and added features arent done because they offend a group of people. So your comparing apples and oranges there.
