The movie itself isn't spectacular in my opinion and I'm not especially attached to the story or characters so it's not nostalgia. I fundamentally disagree with Disney's approach towards it. For Disney to do take this approach, they should think that 1. the movie is racist and 2. this amount of racism is so severe that people should not view it. I don't think think that the movie is as racist as many try to make it out to be and even if it was, I don't think the movie should be buried. If anything, I feel that it's a landmark movie in the fight against racism at the time given the awards to the actors and the main plot.
If people must be taught to be offended by every little thing and then such things must be censored, racism increases its power over society only in a different form. I would like to see more people learn to appreciate what the film does well and learn to forgive for the parts that could be done better. I don't want to see people who would never try to intentionally offend anyone fear being labelled as racists because society is overly critical of anything even potentially racially insensitive.
Apart from if/when Disney releases the movie on Disney+, I think it's good for people to form their own opinions about it and know it's OK to like many of Disney's products but still dislike things they do as a company.
