What if your perspective is limited and your experience is not universal? When neighbors say, "This hurts me!" what if, instead of insisting "No, it doesn't!", we listened and responded by changing the hurtful thing so that the parks are fun for everyone?
That's the approach Disney makes with guests all the time. Able-bodied people never had a problem with curbs on Main Street or stairs in the Space Mountain priority access queue, but those things really hurt the experience of people with limited mobility (a "small minority" to be sure). Disney spent a lot of money to change these sorts of things (sometimes voluntarily, sometimes by force of legal action). After a minor inconvenience to park guests, the result is that the fun is accessible to more people.
I get that you're not offended by the association between Splash Mountain and Song of the South. Lots of people aren't. But some are, and Disney sees fit to address it now. We can (and will!) disagree with their proposed solution (Princess and the Frog overlay), but can you see how these kinds of changes can result in a better experience for all?
Or at least recognize that Disney is trying to sell access to its art and being associated with racism is dangerous to their business.
