Curious what you meant by that. Care to explain?
With the loss of majority status, it becomes difficult to dominate the political discourse like Hindus do today. Just like how it was impossible to think of a non-white person becoming President of the US, it is also impossible to think of a non-Hindu holding any serious power in India for the foreseeable future.
Note for those unfamiliar with India - the language Hindi is unrelated to the religion Hinduism. Its possible to be a Hindi speaker and not a Hindu and also possible to be a Hindu and not a Hindi speaker.
Lets I digress. You can be a Hindu today if you want. Just start incorporating Hindu philosophies in your life. Choose an atheist one if you like.
PS: Not advocating anyone to convert to Hinduism. In fact I think that the lower castes should abandon Hinduism if the upper castes don't reform fast enough.
the last prime minister was a Sikh, the leader of the party which was in power for the last 10 years was an Italian Catholic.
According to this:
https://en.wikipedia.org/wiki/Assault_on_T._J._Joseph
it was a Muslim who cut off a Christian professor's hand in South India. His wife committed suicide because he was fired. Of course BBC, Gaurdian, Firstpost and all other far left websites will not report this. On censorship happy sites like HN and reddit they have successfully created massive propaganda against the Indian government. I can spout nonsense as facts too. Here are example of some 'facts' for you then:
Maybe Obama is a Muslim according to this: http://www.conservapedia.com/Obama's_Religion
Maybe Merkel is a traitor according to this: http://www.breitbart.com/london/2015/10/29/hundreds-germans-...
Maybe Bernie Sanders is a communist according to this: http://nypost.com/2016/01/16/dont-be-fooled-by-bernie-sander...
OP is parroting the conspiracy theory that millions (still a small % compared to India's billion+ population) do because they cannot digest seeing Modi in power. I can go full conspiracy mode and point out who owns left wing media outlets but I don't think HN is a place for such discussions. There are hundreds of report of Hindus being killed in minority rich areas in India, but unfortunately these incidents aren't covered in BBC and Gaurdian because Hindus are a dying majority in India.
