Google "Little Black Sambo." I assure you, this is a well-known term in the States.
The book is out of print. I know because my mom used to read it to my brother when he was a kid. I had never heard of the story at 24 years old. It's likely one of those things that has died off the past few decades.
Still, I can only imagine that people made an irrational correlation because
it's a children's book about not-black people. It's a story about an Indian kid who wanders into the jungle, and in order to keep the Tigers from eating him he gives them his things. In the end they are all trying to be the most magnificent Tiger, start clawing and biting at each other, and in the whole mess Sambo gets his stuff back. Even if he's called Little Black Sambo (his mom is Black Mumbo and his father Black Jumbo), none of the characters are drawn black. They are all clearly of Indian decent. What with taking place in India.
I don't mean to sound like a prick, though I realize my tone must sound as such, but I'm trying to figure out ...y'know what? Nevermind. It's a time long past. It's like how me and most of my friends had never even heard of the term Porch Monkey until Clerks 2 (and then I realized why when I watched Dumbo with my niece. Now THAT is some interesting look back into American culture).
Point is, people that are entering their 30's don't even know a bunch of these terms. We're past when this stuff was a big deal. What we have now is a nation of bleeding-heart liberal white people that are too damned afraid to poke fun at any other color, even if they do it to each other. It's fine for my friends to call me a whop-dego and I can call them krauts, but the second I make foul comments to a black or hispanic? Now that's just too far.
What I'd be more concerned with is who put the word sambo in there with the intentions of seeing something related to black people. If they claimed it as racist then clearly they were intentionally looking for some sort of correlation, one that no one saw until they were educated.
