Nationalism control people since childhood

keyword: Nationalism, Childhood, Control, Propaganda, Education

I’m interested in what makes people become nationalism. Because as far as I can remember, we are all instilled in us to love the nation, religion, and the King. We are cultivated by various media including the Internet, television, and our daily activities for a long time until many of us see it as commonplace and don’t question it like fish don’t know they’re in the water. My interest in nationalism led me to the following questions:

• Is nationalism really improving our country?
• Is there anything that makes people nationalism and they don’t even notice?
• Is nationalism really making our country move or block our vision?
• Who is most benefiting from nationalism?
• Can nationalism be a tool for the benefit of some groups?
