Yeah that wasn't a great moment, but if you look at the context for that you'll see that it wasn't even talking about a black person. It was just an expletive, like saying "motherfucker" or "son of a bitch" etc.

Keep in mind that outside of USA the N word is not nearly as charged politically and racially as it is within the USA. And PDP is Swedish IIRC, not American.

Edit: my point is that his usage of that word - which AFAIK only happened once - is not indicative of his character. It's just indicative that he was really angry at that moment and human brains for some reason use expletives in those cases.
