I can't believe that I'm paraphrasing Mean Girls, but there was something like "if you call each other ****s, you make boys think it's okay to call you ****s" or something like that.
I think that as a
joke it can be used inside the group the slur is directed at, but
never by others (unless quoting for some good reason), especially when it's a member of a group that created the slur. I flip every time a guy calls a girl a ****, same thing applies to straights vs gays and blacks vs whites.
Concerning n word - I don't think you should get angry at foreigners who don't know the exact meaning of the word - educate them nicely instead. those who understand, however
