It is very evident if you read the old (pre-1960) children's books put out by the Stratemeyer Syndicate.
The the books were originally sprinkled with Blacks, American Indians, Jews, Orientals, Hispanics, Italians and Eastern Europeans. In the early sixties they decided that these portrayal of these citizens was "racist". While they probably were a bit what happened next was a pogrom that any Czar would have been proud to set his name to. Since they were rewriting the books to shorten them from 25 chapters to 20 why not just remove those troublesome minorities. Which is what happened.
Trader Joe should respond that they refuse to whitewash their store and products. That anyone who demands they do so are being racist.
