Yo, thanks. He says that my arguments aren't valid and that he tought that i was smarter than this. I also hate the fact that he has popolar boy humor and he says that It's ok to joke about this because he's saying It ironically... Like, when we are on call and there's silence because we both don't have anything to say he just spam the N Word and when i say to shut the fuck up he keeps going

... your friend really ought to learn to keep his mouth shut when he’s asked to :/ 
i think that sort of person lacks basic respect for others, given that they use the ‘n’ word and make jokes about it, even when they’re being told to shut up
