The strangest Intertoob video of the year so far. And of course it's from Japan...
I showed this to some acquaintances at work, and the first thing that they took note of was the use of camels to depict Afghanies/Persians/Arabs(?). Obviously that pushes a button here in the US, where black people were once commonly represented with apes or monkeys in cartoons and in political art going back to the 1800s. So, that left me wondering if the Japanese have any history of using animals to depict different racial groups.
From what I've seen, it doesn't look like it. Apparently the original Cat Shit One was set in Vietnam, with Americans as rabbits, the Vietnamese as cats, Japanese as monkeys, and so on. The choice of rabbits for US soldiers is apparently a bit of word play. The Japanese word for rabbit is usagi, which can be broken down into "USA GI." The author's explanation is that he used cute animals as a means of shocking viewers as he feels that movies have desensitized people to depictions of violence against human beings.
