Yes cause hindus are limited to having just one hero ??So, I presume you acknowledge that Marathas was no empire and they had no emperors.
One doesn't need to acknowledge Shivaji to be 'Indian proud'. Hindus already have a hero named Gandhi who humbled a mighty empire with nothing more than the doctrine of non-violence. He continues to be the most respected leader across the globe and a beacon of hope so many. So why would Indians, especially Hindus, need a second rate king Shivaji for that purpose? This Shivaji is not a hero to Indians, except for Hindu extremists who can't find any real Hindu heroes who took up arms and had a limited success. Marathas is all hype, cooked up by Hindu nationalists.
