Their are some innacuracies on the article. India is at least 80% Hindu. I have a theory about culture. Its kind of like a negative feedback system.
If their is a sharp decrease in a certain culture, then the population will realise this. After all its human nature to only appreciate things once we realise how little we have or how precious something is. Therefore the government will realise that the culture is in danger and try to rejuvinate it. Once the culture has become the norm again, there will be a certain apathy towards it, and so the culture will become less popular, government puts money in to it..and therefore the cycle starts again. Its like an up-down affect. With that Christian Sonia Gandhi in parliament we're not going to get very far though. She pours millions in to conversion schemes, and so the BJP are fighting fire with fire and going around converting tribes. Its a common misunderstanding that Hinduism doesn't convert others. People think that just because all religions are a viable path to God, then theres no need for conversion. This is incorrect. Krishna said that those who spread his message are close to him. Although all religions are a viable path to God, that doesn't mean that they are equal. Sorry to burst the bubble, but Western religions are considered 'Mellecha' ( i think that how u spell it?)which basically means that they are not spiritually in tune. Sonia Gandhi needs to be given the boot and the BJP needs to come back, and promote Vedic culture.
