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.
Randall KennedyIn 1619, when there are reports about the first blacks brought to British North America, they are referred to as N-I-G-G-U-H-S. Well, it doesn't seem that that was meant in a derogatory way. It seems merely descriptive.
Randall KennedyThere are some people who make a big distinction between n - a, which they say is OK, and n - - . Now, in my view, it's important to know about that distinction, because some people put a lot of weight on it. I don't.
Randall KennedyWhat people should do is explain to their friends, to their neighbors how they feel when they confront the word n - - and why they feel the way they feel.
