Are you offended by racial slurs or other types of name-calling?

If you are, is it simply because of the word and its meaning? Is it because thats what the person who is calling you it thinks of you? Is it because that person is TRYING to offend you?
Does anyone else besides me not get hurt or offended when called a name? I just don’t understand…words are just words and what people think of you means nothing.
Does anyone ever think back to the origins of some bad names and realize that there really is no need to be offended..?
