It was George Bernard Shaw who said:
“Patriotism is, fundamentally, a conviction that a particular country is the best in the world because you were born in it.”
What a profound observation!
In fact, similar unfounded convictions of superiority relating to each group (linguistics, racist, regional, religious, caste....), based on the single most fact of one's being born in a particular group, is the cause behind most conflicts among humanity!
I wish we humans begin to value the accidents of our birth, a little less!
