Mr. Gupta, you are right. How much differences may exist among the various constituents of the Sangh Parivar, they are still one family based on hatred toward non-Hindus, believing in the medieval theory of Hindi-Hindu-Hindustan, theory that India is a Hindu homogeneous country! Therefore, they'd always be together at the end of the day. That doesn't surprise many although. On the other hand, other political parties also have not done much for the poor, downtrodden society of India. They didn't do enough to uphold the law of the country, they couldn't provide much justice to many atrocities perpetrated against the non-Hindu Indians! And there exists the opportunity why the Sangh Parivar would survive in long time to come--it would still be a force for years to come. So, these media speculation of BJP, RSS, VHP falling apart etc. should NOT be considered seriously.
