People have been killing each other for millions of years for land and power. The idea they  were killing people just for a flag is ridiculous. In fact nationalistic wars were  always quite civilized and chivalrous compared to the religious  and idealogical wars which were horrific. 
  
 Nationalism does not at all teach you to think you are better. In fact many a nationalistic Briton and German went to other countries to help complete strangers fight for their independence.

When you're spinning WW2 and the Holocaust as more 'civilized' than the Crusades you're already living in ignorance. When you attempt to spin the European Colonial age as a positive and ignore the subjection and human rights violations you are insulting the martyrs who gave their lives so that their children could live free of European oppression.
