You gotta fight for something.
People go to Disney to be entertained by stories, rides, attractions and characters that people have grown up with over the last 80+ years. When something threatens to change any part of these it is cause for concern. Some, it makes sense, and others not so much. This is a prime example of something that doesn't need changing for being offensive, inaccurate, or broken down. Yet once again a beloved ride is being "corrected" just because.
You might not have an attachment to it, which is wonderful for you. I dont have attachments to the dumbo ride, but for those that I do, I am going to take every opportunity to say "***?"
