To explain my point, I have to delve into history. As explained in my article, “What is India”, in my blog: justicekatju.blogspot.in (as well as in the video on the website: kgfindia.com), India (in which I include Pakistan) is broadly a country of immigrants like North America. The ancestors of 92 to 93 percent people living today in our subcontinent were not the original inhabitants here, but came from outside, mainly from the northwest (the original inhabitants being the pre-Dravidian tribals). People migrate from uncomfortable areas to comfortable areas, and India was a paradise for agriculture, with level land, fertile soil, plenty of water for irrigation, etc. It is for this reason that India has so much diversity— so many religions, castes, languages, ethnic groups, etc because each group of immigrants brought their own language, religion and customs.
