The same argument can be made about people who are triggered by this edition of the book. You can just not read the new edition instead of pushing for and celebrating the silencing of its owners.
The "owners" (who likely don't have a imaginative bone in their entire skeleton), if you'll pardon my vernacular, should stay the fuck out of the authors original work instead of mucking around with it, particularly inane changes like the removal of the word fat.
And by pushing a new addition of the book while discontinuing the originals they seek to erase the authors original work. If anything this particular addition should have a large CliffsNotes banner on the cover.
