Does it matter if nationality is a man made social construction, if it's working?
I feel closer related to Swedes than I do to Norwegians. I would rather be surrounded by Swedes in my day to day life, than I would be Norwegians.
Some nations characteristics I openly despise, Somalia as an example.
I know I'd feel rubbish being surrounded by Somalis in my day to day life.
Nationalism is about TOGETHER striving towards a goal for the nation at large. People not sharing this vision isn't welcomed in a nationalistic society.
All people in a nation helps influencing the nations will and goals. That's why it's on the positive side if people follow some pre-set ideas and goals.
As an example, Sweden's goals include healthcare for everyone and womens rights...
I for one absolutely despise some cultures, and don't want them to influence my nation. Gypsys comes to mind, so does Somalis... As their goals conflict with Swedens.
