You have sort of explained "what is citizenship", complained about some random ideology, and completely failed to answer either of my questions. My country is NOT my family. My "nation" (whatever that is... a replacement for a tribe or something?) is NOT my family, nor even my extended clan. Why do I need to have "family" at a scale of millions of people, almost all of whom I will never encounter? A reminder of the still unanswered questions: Why does citizenship matter? What does any of that have to do with the difficulty of changing citizenship?
