You see, when you create a flag, you immediately do two things: you create an in-group, a group that's meant to be represented by the symbol, but then, inevitably, you create an out-group.
Vidite, kada kreirate zastavu,  odmah činite dvije stvari: kreirate unutarnju grupu, grupu koja bi trebala biti  predstavljena simbolom, ali uz to, nesumnjivo, kreirate i vanjsku grupu.
