No, I'm a cracker. And, according to Peaguy, a Slovakian prostitue.
But I used the word 'nigger' once when I was learning English and I got into a lot of trouble over it (that's how I learned what it REALLY meant). Also, I worked with this one guy who was a total classless hick, and he used that word like most of us use "hello". He's the only person I knew who really said it a lot, so my general impression of people who use that word is pretty low.
