Of course I'm only a redneck myself, but I've always wondered why the crows in Dumbo haven't been censored out. It seems to me that they are a much more negative stereotype than Uncle Remus.
The 'Black' crows in Dumbo are the only characters who show any kindness towards the little elephant presumably knowing what its like to be societal outcasts. If anything its an anti-racist statment. And they sing the best Disney song of all time, 'When I see a Elephant Fly'.
