India is actually trying to forcibly create a “nation”.
In actuality India is a union of multiple “nations” - the Punjabis (many of whom are Sikhs) are culturally, linguistically, religiously and by genetic mix different from say the people who live in Calcutta (Bengalis) or those in Bombay (Maharashrians) or in Madras (Tamils) or in Bangalore (Kannadigas) or in Hyderabad (Telugu).
Each of these groups have a different language - and not only a different language, but a different SCRIPT (writing) and millennia of separate history
Another British Empire foul-up.
