Just for reflection, let's ask ourselves why that is:
I don't think it is fair to say that it is racism. Realistically, even we know there is hatred in this world, it is not the majority.
It is because they are getting rid of an attraction that is majorly a success in the theme park world to this day, incredibly popular as a theme park attraction can be and have low reputation in recent decade to do anything as amazing as what is already there.
It is something that Disney has never done, they close something the majority have a fondness and joy for, to be replaced by something they hope is just as good, and very few having faith or a care that it will be superior. They have a lower reputation in the industry as in the past and have had a terrible commitment rate reputation of things being announced and not happening.
