From a cartoonist's perspective, Walt Disney was basically the Antichrist. (Or still is, if they managed to put his brain in an audioanimatronic body -- the premise of one of my cartoons.)
Top Ten Reasons Why:
1. Disney absorbed stories and folk tales like a giant blender, ground them up and turned them into commercialized mush. Disney's Snow White became everybody's idea of Snow White. Or Toad of Toad Hall. Or whatever. His formulaic crap eclipses the originals.
2. Disney's "imitation of life" poisoned the genius of American cartooning. No, we don't want fantasy and fun. We want creepy, rotoscoped puppets. Yeah!
3. Disney was a fascist. His cartoons had a relentless theme of conformity. The lesson is always fall in line, do what you're told, clean your room, take a bath, you rotten dwarves, obey.
4. Disney hated strong women. He constantly punished them.
5. Disney was always killing moms.
6. Disney had a creepy, pedophillic obsession with little boys' rear ends.
7. Disney infected the American imagination with marketing. Hey, were not creating stories about characters -- we're selling product! Mickey Mouse began as a cartoon character. He turned into a !@#$ logo.
8. He created an empire that continues to infect the American imagination.
9. His empire helped kill traditional cel animation with ubiquitous CGI.
10. Disney is the example that everyone tends to follow. Create an honest story? Speak from the heart? Who does that anymore? Almost everyone thinks of story and character as products to be designed and marketed for various demographic niches. The goal -- find the perfect formula, then repeat. Create art on an assembly line. Turn artists into replaceable parts -- hired hands. Subordinate the vision of the individual artist to the corporate mission. Avoid risk and originality at all times.
