You are right. We eternally hate each other. We are like a jar of scorpions even if one tries to come up we sting and pull it down.
You know in other countries like France, German , Australia I have seen that they are proud of their heritage. I mean countries like US and Australia which were traditionally convicts are proud of their fellow men. But India was blessed with so many incarnations and spiritual people yet we abhor each other.
I share your grief and pain. May be this realization is the first step towards better future.
