Nationalism is rarely not racist. It is rarely not anti internationalist. It is rarely content with single nation closed borders without influence abroad.

all nationalism tend to an Us and Them mentality, and to a superiority of US, and to a special pleading for that Nation. In time all nationalism becomes Our Nation is Best, and deserves more, and other nations are lesser and deserve subjugation. 

every time. Just look at how people insult each other over flags here - I am called a frog all the time asn surrender and cheese gets mentioned fairly frequently. I am actually a Brit, who lived in Ireland for a long time, and now live in France. So the stereotype does not fit, but is still being flung by retarded Amerifats who think they are the only people with freedom because they have guns. (I have guns... I hunt, it is no big deal) 

it is a small example - but it is the nationalism that leads to war, colonialism, and genocide. 

it is built in.
