the newfound love for a particular personality is not "nationalism"...it is more related to the frustration with the current system and weak leaders at the top...Maybe Hitler ignites their fantasies of how to turn around a country single handedly. As young teenagers, it doesnt really matter whether the turn is for good or bad. Constitutionally India is Secular so no point talking about a particular religion. However, you maybe right in saying that young indians want a strong india.
