One of my responsibilities at Reznet is updating the redlines section every weekday and during the weekend if I'm feeling partiuclarly zazzy. You come across all kinds of odd things with a web crawl like that.
One of them being a grammatical error that most word processors just can't catch: Native American. Unless you're dealing with journalists who don't lean on spell check, you'd spell it just like that. Capitals, two of them.
But those journalists who do rely on spell check like a crutch end up spelling it "native American."
