My personal views and on a very lighter note, there can be a theory, a psychological reason, a subtle one, and that is, the fact we were actually a divided lot for most of our history, even a slightest interest in history will tell you that the biggest democracy on planet wasn't a democracy for most of its history. The doctrine of unity in diversity is actually a very recent one, we have been independent states for the most of our known history. These states were mostly on the basis of region and language,( not religion as many people may think), though there were national figures in Delhi(sultans and mughals) and Patna(Guptas and Mauryas) but Dravidians were mostly oblivious to that supremacy and other states had there own rulers who were either completely independent, or at the most, accepted the bigger power by paying taxes but by and large managing states on there own. So basically we were historically divided.
So may be this is the psychological base for some psychos who are on the way to divide this country once again just like we were few hundred years ago. Can somebody please tell these retards that times have CHANGED, we leave among trains and flights now, not between bullock carts and horses. These guys are mentally sick and are very bad student of history. They never understood that why Chandragupta maurya won against Alexander the great. They studied Peshwas but never understood why were they defeated at last battle of Panipat, they never learnt why East India company managed to enter this country and rule with a handful of people over millions of us over a period of 200 years.
These maniacs must be stopped as History has the habit of repeating itself.
Thanks for your patient reading.
