Nationalism & Globalism

Nationalism.. why ppl love country, loyalty?

How much it is possible to love strangers of a new country?

How much it is ok to let them inside your country? ( rethink about qn 1)

How to know how to help your fellow humans ? How to help your own country citizens?

While talking about this , what happens to our loyalty and humanity upon global issues , like poverty, war etc..?

We all knew that we love our own nation.. We have some loyalty towards the land we are born. We accept and be tolerant with our own folks.

 How did it develop? 

Are we loyal to the country or to the group we belong to OR to the similar kinda people with our culture and values.?

If you take europe, there are many small countries and people have similar values /culture, even may be language. Then why is that we are loal just to our country, but not neccessarily somoene who is more like us in terms of language or culture or skin color. :) 

We all talk global problems.. we want to welcome poor refugees? But are we really love our neighboring countries or people? Where is this difference coming from? Can we clearly define what that is..

yes .. On my vetti time , with my vetti brain ponders over..lol
