In reality, India was never a secular country and there was no secular Prime Minister in that country. Both the BJP and Congress parties have disclosed this since the beginning of the 1980's. Teaching history according to their own way is another expression of their ugly communal belief. However, I do believe that having more objective history textbooks would be beneficial in reducing the animosity that exists between South Asian neighbours. The problem is that a lot of the distrust built up over the years is due to the respective governments using propaganda to win over public sentiments.
Every country presents history with a nationalistic angle.
The way children are taught about history will definitely effect their feelings about other countries, religions and people. However, in India, most schools are secular as children from all religious groups are enrolled together. A. Rastogi, USA Indians have a definite right to rewrite history if more facts are uncovered and more research is done. Also the fact is that we study the history of medieval India much more than the 2000 year history before that.
