Regarding "Song of the South", I bet they would release the movie on home video if Uncle Remus was a kindly wise homosexual. That would be considered ok. But for him to have been a slave and too happy as a slave, we're going to censor such a movie.
It's interesting to consider what they censor compared to what kinds of offensive movies are considered to be ok nowadays.
Sat. Night Live did a TV Funhouse animated bit "Inside the Disney Vault" where Mickey takes two kids and shows them things like the _original_ version of Song of the South that Walt wanted to put out: It has Remus singing "Zippity doo dah,
zippity-ay. Negroes are inferior in every way."... "I heard he was anti-Semantic!," one of the kids tells Mickey. "Semitic,"
he corrects her. (It concludes by showing the Lion King's
Scar as a lawyer who later sits in with the panel of
The View.)
Then there was the clip of Bambi 2002 that has the young deer doing a rap song...
Some of the films from the 30's like "Kentucky" with Loretta Young featured happy, subservient slaves. Also "Jezebel" with Bette Davis. AMC channel used to broadcast films from the 30's until about fifteen years ago, then they decided they wanted to be more commercial...and they added commercials and stopped showing the old-time films.
Wouldn't that be Uncle Ream-us?
