Or how African Americans in the US often call themselves n****, but it is a bit racist if you call them like that. Try it and see what happens.Thats actually weird, because my knowledge was always a Siptar is Albanian living on Kosovo, it is a slang, guess same how feckers says ciganin vs rom for gypsies, i surelly wouldnt say anything silly like making it even close to n word, the hell.
Also, how Albanians call themselves is a bit different to 'Siptari'.
