oh you don't want me to mention Pakistan? that ashamed? ok, I won't embarass you further on that then.
So in India, the minority muslims proportion has grown up significantly since independence; in spite of having more muslims than almost all other countries, Indian muslims do not get radicalized (barring some rare exceptions). In spite of being one of the poorest countries in the world, Indian muslims, Christians, Jews, Hindus, Sikhs, Jains, Bhuddhists etc have learnt to together build a nation.
And then there is racial diversity as well - Tamils, Maratha, Punjabis, Gujrathis, Nagas, Gurkhs, Kashmiris, Bengalis,, etc etc all freely move around (again barring rare exceptions) and build their familes across the nation.
then we come to language diversity - Tulu, Tamil, Malyalam, Kannada, Marathi, Telugu, Oriya, Assamese, Hindi, Punjabi, Gujrathi, etc etc - dozens of languages and hundreds of dialects...yet they all get along and build beautiful vibrant communities across the nation.
If you don't know this you live under a rock and the rock is called wanton hatred born of ineptitude.
