Well, this one is possibly purely personal - but I know that there's no way in hell I'd feel comfortable using "nigger" as anything but an example of a prejorative term. It's one of those words that I don't know can *ever* be reclaimed, partially because of history, partially because of ongoing racial issues. I'd probably argue, actually, that it goes for all racial epithets ... it's just that I haven't seen many efforts by the Jewish community to reclaim "kike". (Nor do I want to. :) )
