Is a Hindu Nation our Birth right. Should India declare her as a Hindu Nation ?

We have seen brothers fighting and killing each other right from the days of Mahabharath. We have seen kings and jamindars within India killed their own community for the sake of lands. The rulers within our country destroyed each other of their own so called religion for the sake of capturing power and dominate others. Religions have born only to take the humanbeings to the hight of the civilization and the religions are not there to teach us to destroy each other and behave like a beast. Therefore instead of fighting amongst the different religious people to know which religion is superior let us take the teachings of the great saints and founding fathers of the religions and live peacefully and spare others peacefully to live. If true secularism is followed and everybody treated as brothers and sisters then this universe will be like heaven.
