AThe main problem I have with lists like these is that they confuse stereotypes with racism assuming they mean the same thing. While stereotypes can be attributed to racism, most of them merely stem from ignorance or common association.
Also, what I found funny was that Commando Duck wasn't on that list, even though a sizable amount of the short is spent showing them in a negative light and as untrustworthy slobs.
Of that list, only "Sunflower" and "Thursday" seems to have a hint of racist intent. Although "Thursday," while drawn in a now very unpopular characature, is more simplistic rather than racist. It's pretty much the same premise as Jungle 2 Jungle or common Mickey premises like Mickey and the Seal. It's more of his supposedly primitive upbringing rather than his ethnicity that makes him seem more like a lost puppy in that story.
Stuff like the those siamese cats pretty much fall under the "cheap joke stereotype." Sort of like British characatures that have huge noses and extreme overbites drinking tea and saying "cheerio" all the time. The Indians fall into the similar camp: a product of the hundreds of westerns popular in Hollywood and on television.
I have a very hard time finding Remus or the crows racist, mainly considering how they are some of the most positive and enlightening characters in their respective films. The association of blacks with crows never really bothered me, probably because it was used well in Fritz the Cat; it seems more like a dated stereotype than anything malicious. The criticism of historical accuracy in Song of the South is valid, but a bit silly when used as proof of racism. It was made at the height of the "classic Hollywood era," which were more geared toward positive moral messages and happy endings rather than historical accuracy. I highly doubt they had an agenda to rewrite history.
Don't really get the King Louie lynch, since his personality is pretty close to Balloo (whose conveniently not mentioned), except that Balloo has slightly better moral fiber.
The guy was apperently not paying attention to the story, since as far as I could tell, Sebastian begain his music number because he was concerned with Ariel's well being on the surface and wanted to convince her that the surface wasn't as great as she thinks. I kind of doubt there was any intent to spread some kind of hobo philosophy. The "blackfish" is indeed a dated characature that I'm surprised to see in the film, I will admit, although on a purely character design basis.
The Aladdin merchant was is really just some old codger with an accent trying to sell the viewer his merchendise/tell a story than anything. Those lyrics are likely pretty accurate given the medievel setting, though their ommission is competely understandable
While these stereotypes (especially in Disney productions) are in bad taste today, I think it's a stretch to consider the much of these listed here truely racist--just ignorant.
