What's sad here is that most of us do agree with you up to a point - we're really sad that the ride has to change. We will miss it too, maybe not as much as you do but it is a cherished part of our core memories with Disney. And I do mean that. You might feel betrayed that we are all willing to let it go while you still feel the urge to fight on to save something that means so much to you. And a couple of trolls on twitter and here will pour gas on the fire by calling the ride itself offensive just to rile you back up. I didn't mean that in the words you took apart by me, you missed the meaning of my message when looking at it only one phrase at a time.
If you can set aside your own feelings for a moment, try to put yourself in someone else's shoes for a few minutes. Clear your mind and think only about a person of color who sees every white Disney princess get an attraction or a ride. You have Snow White's mine train. Belle's restaurant and shows. Cinderella's castle and restaurant. Rapunzel has a ride in Tokyo. Sleeping beauty's castle at Disneyland. Frozen's Elsa and Anna own the Norway pavilion at EPCOT. Ariel even has a ride and she's half fish!
Then realize that 13 years later, Disney's only black princess has a rack of dresses in a gift shop and a generic photo-op. Meanwhile, you hear of rumblings that a really old ride is based on characters in a movie with racist stereotypes. And then you realize that the really old ride could be converted to tell the story of the black princess. Wouldn't you draw the same conclusions that others have had - that maybe an old ride could be changed to make a difference to people of color instead of being associated with a movie with a racist ties? There is nothing sinister at play at this line of thinking. There is no sketchy agenda, no backroom dealings and no conspiracy. In this situation, it's simply overdue to make changes and one ride re-theme will mean a lot to a big group of people who feel under-represented at Disney.
Hopefully if you made it this far you realize that there is an entirely separate side of this situation to possibly consider. Please remember that the new generation of disney fans may never have had the chance to fall in love with Splash, for them it's either unknown or just a cute ride that is looking old now. I hope that you take the time to really process everything that I have written here. I don't know you at all, but I feel like you're hurting deeply. I didn't realize that before. You should consider finding healthy ways to process that sense of loss and how to grieve the eventual passing of your beloved attraction and how to best honor it. I sincerely say this to you.
