One must be deeply disturbed to find this movie deeply disturbing...Song of the South crosses that that vague line between just being offensive and being deeply disturbing.
Using the 'logic' that people use to justify not releasing this movie we could also say that...
Snow White and the Seven Dwarfs is offensive to drarves/short people. Also, is Snow White the fairest/prettiest of all because she has fair/white skin? Why?
The Three Caballero's might be offensive to Mexican people.
Cinderella is offensive to women with big feet.
Lady and the Tramp is offensive to homeless people.
Aladdin is offensive to middle-easterners.
The Sopranos should be cancelled because it's offensive to Italians.
Lucky Charms and Irish Spring commercials are offensive to the Irish.
There are many movies which might be offensive to Japanese.
Jacob the Liar should not be released because it didn't accurately portray the holocost.
...and as Luv2Roam stated, there are probably too many movies which are offensive to women to even list.
Why do we worry so much about offending one group of people and not the rest?!?
