Nationalism is a concept brought by the left during the XVIII century
Before people werent concerned by this nation shit, they were just dealing with others from the same geographical location and they shared their culture and their language with people living around.
But in this modern world, people killed all geographical cultures because states are too strong, and then they complain about being "extinguished" or some shit. They think nationalism is the solution while it's the exact cause that lead to the problem they try to fight.
