I get very offended when I hear the 'n' word and tell that person to never say it in front of me again. I'm white, which shouldn't matter, but just clarifying. I find it the worst racial slur. I'm not even sure why! My best friend's boyfriend just told my boyfriend and I that his little sister is mentally retarded. I now find myself feeling really bad if I accidentally let slip "I felt sooo retarded," or "He looked so retarded" around him. I grew up hearing that word, but now, even though he never said it offends him, I feel it is a bad word to use as well. As for any other racial slurs, well, no one's used them around me. Just those two. But I'm sure I"d be offended if I heard them used, especially in a hateful way.
