Nationalism is a concept that people just do not get, hence the past couple of posts. Nationalism breeds war, imperialism through acts of russianization(process of moving people to a captured territory and forcing them to breed after exterminating most locals.) and nazis. Ideas of nationalism were spread by napoleon, they haven't been something we've been thinking all along.
Lets use several examples for this:
Ottomans dominate eastern europe, yet do not attempt to say we are better then you because we're turks, they just collect taxes.
Scandinavians: Its kind of obvious they didn't rush to battle thinking "im finnish/swedish/whatever bitch". Instead they killed and raped for money.
2 examples of nationalism:
Nazi germany, hitler looked to exterminate everything that wasn't the nationality he defined was "perfect."
Serbian invasion of bosnia: they werr engaging in ethnic cleansing, so to speak. Killing in the name of preserving their nationality in an area.
I'd add more but its 4:20 am and i'm on my phone
