In which case i could argue that nigger is not racist, based on context. My mother used to sing eenie meenie minie moe, catch a nigger by his toe. She doesn't have a racist bone in her body. The context is simply that's what the actual song was before PC came along and they had to change it to tigger. She was not taught it as a racist term, she did not use it as a racist term, she just used to sing the word nigger, because it was just a word.
Next time i'm called white i'm gonna cry and pull out the racist card. I'm Caucasian, stop being so bloody offensive, how can you have such a sick mind!
Ignoring what i say above, your argument would be flawed. Black people often refer to each other as niggers. so that then goes back to is it simply racist because the receiver believes it is being used in a racist manner. If a white and a black person both refer to the same person as a nigger, why is one being racist and the other not? Or are you suggesting it is impossible to be racist to your own race? That seems pretty illogical.
