Ethnicities are part of who we all are. While I’m not particularly sensitive about my German ancestry, I see all sorts of ethnicity demonstrated in films. Yes, it can be offensive, like Amos and Andy, but how about the landlord/handler in “No Way Out?” Is it likely that a Russian would find it offensive, because the accent is over the top?
Has anyone seen “Porgy and Bess?” Stereotypes all over the place, but it’s also pretty accurate in its portrayal of the dialect in many black communities.
I don’t believe “Song of the South” deserves obscurity. Amos and Andy probably does, although it was a program that allowed the new medium of radio to survive and prosper.
