Other forms: jingoists
Jingoists really dislike people from outside their own borders. Jingoism is an extreme form of patriotism that often calls for violence towards foreigners and foreign countries.
Patriotism — a love for one's country — can, in certain cases, turn nasty and go beyond wishing for the welfare of one's own homeland. That's when a patriot becomes a nationalist. From there, it's only a short step to becoming a jingoist, one who not only waves the flag of their country but believes that all other people are threats and should be treated as such. An obvious example of a jingoist was Adolf Hitler, who stirred up fear and anger towards outsiders that led to world war...and much worse.
