One was a horrible case called Oliphant v. Suquamish Indian Tribe which denied tribes the right to criminally prosecute non-Indians who commit crimes on their reservations. That decision has had horrible consequences for law enforcement on Indian reservations. But in that opinion Justice William Rehnquist cites language from the 1830s to explain why whites didn't trust tribes to exercise criminal jurisdiction. They were savages.
Go back and take a look at what some black writers were saying in the 1820s, the 1830s. They make mention of how some white people would tell their children, if you don't behave, we're going to put you in the n - - seat. If you don't behave, we are going to make you sit with the n - - s. That's why we know that, by then, the word had become a slur.
Utopian fiction is really boring. I had to read a lot of it, and it's not that much fun. But they're fascinating to me as historical documents. Cabet [Icaria's founder and author of the utopian novel, Travels in Icaria], is writing in the 1830s, and his idea of the perfect society reveals a lot about his time. But his book is uniquely bad.
