Well the same could be said for the word 'skank', it's a derogatory word also.
I agree that no one should call each other the N word but I just get so tired of hearing it in the black community, but at the same time, they don't want anyone else to use it because it's such a hurtful word. If it's such a bad/hurtful word then they shouldn't use it either.
I mean, you can't say it's okay for 50-cent to say it but it's not okay for Paris. Either it's wrong for both or wrong for neither.
