Disadvantages And Advantages Of Nationalism
In Quranic perspecive, Quran 49:13 O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous1 of you. Indeed, Allah is Knowing and Aware. Only advantage is u can recognise each other or get sense of belonging. The biggest disadvantage which come with nationalism/ tribalism is pride/arrogance/ego etc which lead to unnecessary voilence, injustice, war etc.
